769: Implement and Validate all WebGPU Limits r=kvark a=cwfitzgerald
**Connections**
None?
**Description**
This adds all the limits that webgpu has currently. It also validates the values.
The main piece of code here is `BindingTypeMaxCountValidator` and `PerStageBindingTypeCounter` which provides the interface for figuring out the maximum per-stage counts in the pipeline. For each `BindGroupLayout` a `BindingTypeMaxCountValidator`is put together during creation using all of the bindings. Then the `BindingTypeMaxCountValidator`s are combined into a single max. This is then validated against the max limits.
Each commit should be independently testable and are grouped by responsibility.
**Testing**
I modified the wgpu-rs example framework to ask for extremely reduced limits and then tested various examples to verify it properly accepted/rejected based on the actual limit.

763: Remove raw pointers from the render pipelines API r=kvark a=GabrielMajeri

754: Implement MultiDrawIndirect Extensions r=kvark a=cwfitzgerald
**Connections**
Closes#742.
**Description**
These extensions, especially when combined with binding indexing, allow the creation of extremely cpu-efficient gpu powered pipelines.
Adds two extensions allowing various types of multi-draw-indirect
- MULTI_DRAW_INDIRECT (giving `multi_draw_indirect` and `multi_draw_indexed_indirect`)
- MULTI_DRAW_INDIRECT_COUNT (giving `multi_draw_indirect_count` and `multi_draw_indexed_indirect_count`)
This adds what I believe to be an extra restriction on the `*count` family of functions when compared to the underlying api. The buffer _must_ be large enough to draw `max_count` draws, even if that many draws are never drawn. This makes these operations no more unsafe than indirect would be, which is currently safe.
I did not implement these for renderbundles, but there's no reason they couldn't work, so those branches are marked with `unimplemented` as opposed to `unreachable`.
Additional Changes:
- Added some validation to the normal `draw_*_indirect` functions to prevent buffer overruns.
- The DX12 gfx-hal backend requires the strides to _always_ be non-zero, so I modified the normal indirect draws to use explicit strides.
- Made device limits and features `pub(crate)` as they need to be checked in random places in the code.
**Testing**
The change was tested using a modified version of wgpu-rs's texture-array example using a variety of permutations. I have not been able to test regular MULTI_DRAW_INDIRECT on mac, but I see no reason why that wouldn't work.

740: First Phase of Tracing Transition r=kvark a=cwfitzgerald
## Connections
First step in the implementation of #491. https://github.com/gfx-rs/wgpu-rs/pull/395
## Description
This adds the tracing crate, implements a tracing "layer" for chrome tracing, and instruments every entrypoint into wgpu.
Tracing is added as a main dependency. A feature is added called `subscriber` which guards the tracing and default logger implementation, as that adds 3 dependencies.
The main macro is there to make creating a span a simple one line process. This macro will come in useful in the next couple stages. Use of this macro is used unqualified with it imported into scope as that style allows IntelliJ ides to actually find the macro.
I also removed a really annoying warning that was driving me crazy.
This PR does not make sure the logging output from tracing is up to snuff, that will be done when logging output and conversion is the priority.
Both commits should compile individually, so shouldn't need to be squashed.
## Testing
This PR was tested with the wgpu-rs PR on various examples, as well as my personal project.

**Connections**
Related to https://github.com/gfx-rs/wgpu/issues/738
Related to https://github.com/djg/peek-poke/issues/10
**Description**
As of #726 , the buffers have a minimum binding size that has to include the shader struct size. It, therefore, can't be zero.
We can remove the hacks we had previously and switch fully to the idiomatic `Option<NonZeroU64>`.
Peek-poke doesn't `NonZeroU64` and friends, so this made me reconsider the user of it entirely. Today, render bundles as well as the Player already represent command streams using a much rustier method. I tried to move everything to this method now, and I think this is going to work much better, and safer.

* Converts _some_ assertions from `create_bind_group` into `Err`s
* Validates that the type of sampler declared in the bind group layout (comparison or not) is the same as the one of the actual sampler.
**Testing**
Tested locally on the `shadow` example in `wgpu-rs`. ~Will follow up with a PR in that repo with the updated API.~ https://github.com/gfx-rs/wgpu-rs/pull/398

There was a lot of highly unsafe use of serialization based on peek-poke that we
weren't entirely happy with. It's replaced by just serializing the passes now.
Also, switch BufferSize to Option<NonZero>.

728: Documentation Pass r=kvark a=cwfitzgerald
## Connections
https://github.com/gfx-rs/wgpu-rs/issues/378.
## Description
The number one thing that people want to see in wgpu is better documentation, so this is a first step towards that goal. It unifies the documentation and fills it out so most things have documentation that is at least marginally helpful.
Notable changes to existing documentation:
- Removes "a" and "the" at the beginning of short descriptions.
- Always use the phrasing `Describes a...` for descriptors that create objects directly.
- Always use a period at the end of short descriptions.
## Testing
No code was changed, but constant monitoring of cargo doc output in wgpu-rs was used to keep everything completely consistent.

**Description**
This change allows users to optionally specify the expected minimum binding size for buffers. We are then validating this against both the pipelines and bind groups.
If it's not provided, we'll need to validate at draw time - this PR doesn't do this (focus on API changes first).
It also moves out the `read_spirv`, since wgpu-types wasn't the right home for it ever.

712: RODS part 2 r=cwfitzgerald a=kvark
**Connections**
Unblocks https://github.com/gfx-rs/wgpu-rs/issues/359
Is a follow-up to RODS part 1 - #685
**Description**
There is a few things in here.
Thing 1: Stronger assertions on the load/store ops of the depth & stencil.
### Thing 2: rewritten tracking of render attachments
Background: from the usage tracker point of view, each subresource can be in either "extend" mode, where it accumulates a single combined usage, or in the "replace" mode, where it goes from one usage to another, producing the relevant transitions on the way.
The problem turned out to come from the fact that the render pass attachments were always tracked in "replace" mode. This is needed because their track don't have a single state: render pass itself encodes a transition of attachments. However, it also means that there was no way to "extend" the usage in RODS scenarios...
So I could see two ways to address this:
- re-achitecture the tracking a bit more in general, representing it as a sequence of merges.
- introduce the "prepend()" tracking operator that's *only* used for render pass attachments
I opted for the latter as it seems much less intrusive. The render pass attachments accumulate their usage like everything else in the "extend mode". But right before we are inserting the transitions (between the active command buffer and the pass), we turn the tracking of the attachments from "extend" into "replace" mode by installing the "first" usage according to what we expect it to be.
### Thing 3: missing API for RODS bind groups
The original RODS design missed a problem with Vulkan image layouts. When creating a bind group, one has to specify what layout the image will be in. We always used `ShaderReadOnlyOptimal` until now for texture views. However, in RODS scenarios this has to be `DepthStencilReadOnlyOptimal`. Luckily, it's compatible with sampling from the shader, but we still need to know about this when creating the bind group.
**Testing**
Tested on the modified water example provided in https://github.com/gfx-rs/wgpu-rs/issues/359#issuecomment-642167269
Added a few tests to the buffer implementation of the new `prepend()` operator.

715: Implement SAMPLED_TEXTURE_ARRAY_NON_UNIFORM_INDEXING r=kvark a=cwfitzgerald
## Connections
Closes#483. Extends support for #106.
## Description
This forwards the descriptor indexing features gfx-hal up to wgpu.
Note this PR also changes the name of the `TEXTURE_BINDING_ARRAY` to `SAMPLED_TEXTURE_BINDING_ARRAY` to be more consistent with extensions.
## Testing
Texture-array example was simply extended to use descriptor indexing. This works on all platforms that the feature is supported. (thanks @stararawn)
Co-authored-by: Connor Fitzgerald <connorwadefitzgerald@gmail.com>
This is a major change in how the bundles are implemented. Instead of
transparently injecting them into the pass command stream, we are now
treating bundles as first-class API objects and API tracing them
accordingly. The bundle contains a normalized command stream that is
very easy to inject into a native command buffer multiple times.
711: Implement Descriptor Array Extension r=kvark a=cwfitzgerald
## Connections
Blocked on https://github.com/gfx-rs/gfx/pull/3269 and does some funky git overrides to get CI to return meaningful results what will be removed once that PR lands and is published.
## Description
This PR implements the `TEXTURE_BINDING_ARRAY` native extension. This allows users to specify a uniform sized array of textures for use in shaders.
As a corollary, this PR rustifies the Bind Group and Bind Group Layout interface. Two main actions were taken when doing this:
- Types that were able to be shared among wgt, wgc, and wgpu-rs were moved into wgt.
- Types that had references to other wgpu-rs specific structures were duplicated into wgc with wgpu-rs structures replaced with the appropriate ID. Notes were added to the wgc types that they were duplicated directly from wgpu-rs.
From what I can tell, this resulted in a significant reduction in code complexity when dealing with bind groups, favoring strong types over runtime assertions.
Naga validation of arrays of textures was not implemented.
Documentation was added to extensions to help users understand what underlying tech was being relied on as well as the platforms it should be expected to work on. I think this pattern should be implemented across the board for extensions as it makes them much more user friendly to use.
## Testing
There is an example included in the wgpu-rs PR which was used for testing this feature. It worked on DX12, Vulkan, and Metal (MSL > 2.0), as was expected.
Additionally the other examples were run and are still verified to run.

707: Implement Bounds Checking on Buffers to Buffer and Texture Copies r=kvark a=cwfitzgerald
**Connections**
Closes#362, closes#554
This addresses issues found by @gretchenfrage when accidentally writing off the end of a texture causing a DEVICE_LOST error.
**Description**
Adds bounds checks to write_texture and write_buffer, and copy_texture_to_texture and friends. The bounds checking functions themselves follow guidance from the webgpu standard.
This doesn't make wgpu 100% to all the checks required by the standard, but takes care of the ones related to bounds and buffer overruns.
**Testing**
I tested this against all the examples, including intentionally making mistakes in texture copies, with this successfully catching those errors.
**Review Notes**
This code should be picked through fairly closely, as it's very likely there's some typos due to the close-but-not-quite repetition that these tests require. There's a bunch of LOC, but they are fairly boring and should be easy to understand.
I have tried to give assert messages that are as descriptive as possible, but if there is a message that could be changed to be more clear, let me know.
One thing that could change is the location of the functions. I left them where I originally wrote them, before I realized that the functions on queue also needed bounds checking, but they could have a better home elsewhere, maybe even their own file.

704: Pipeline layout validation r=cwfitzgerald a=kvark
**Connections**
Implements a solid part of #269
Starts converting the function to return results, related to #638
cc @GabrielMajeri
**Description**
This change matches shader bindings against the pipeline layout. It's *mostly* complete, minus some bugs and not handling the `storage_texture_format` properly.
The risk here is that Naga reflection may have bugs, or our validation may have bugs, and we don't want to break the user content while this is in flux. So the PR introduces an internal `WGPU_SHADER_VALIDATION` environment variable. Switching it to "0" skips Naga shader parsing completely and allows the users to unsafely use the API.
Another aspect of the PR is that some of the functions now return `Result`. The way I see us proceeding is that any errors that we don't expect users to handle should result in panics when `wgpu` is used natively (i.e. not from a browser). These panics would happen in the "direct" backend of wgpu-rs (as well as in wgpu-native), but the `Result` would not be exposed to wgpu-rs, so that it matches the Web behavior.
At the same time, browser implementations (Gecko and Servo) will check the result on their GPU process and implement the WebGPU error model accordingly. This means `wgpu-core` can be super Rusty and safe.
**Testing**
Running on wgpu-rs examples. Most of them fail to get parsed by Naga, but `boids` succeeds and passes validation 🎉
