763: Remove raw pointers from the render pipelines API r=kvark a=GabrielMajeri
**Connections**
Rust-ification of API, as part of #689
**Description**
The objective is to get rid of raw pointers in the render pipeline descriptor and associated structures.
**Testing**
Checked with `player` and the `trace` feature, and with `wgpu-rs` with the changes in https://github.com/gfx-rs/wgpu-rs/pull/425

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.

747: Custom implement Debug for RenderCommand and ComputeCommand r=kvark a=kunalmohan
This would avoid unnecessarily long debug logs for Render and Compute passes to some extent. I am not sure if it would be helpful to print `dynamic_offsets` and `string_data` under `BasePass` without the content of related `Compute/Render Command`.

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.

739: Remove Peek-Poke r=cwfitzgerald a=kvark
**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.

wgpu-rs works - https://github.com/gfx-rs/wgpu-rs/pull/396

736: Validate sampler type in `create_bind_group` r=kvark a=GabrielMajeri
**Connections**
Fixes#588
**Description**
* Makes `create_bind_group` return a `Result`, and adds a new `binding_model::BindGroupError` enum.
* 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
Co-authored-by: Gabriel Majeri <gabriel.majeri6@gmail.com>
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>.
735: Set descriptor set name when creating bind group r=kvark a=GabrielMajeri

There is a [`TODO` in the code](a02a566841/wgpu-core/src/device/mod.rs (L1428)) for setting the descriptor set name when creating a bind group. It was blocked on https://github.com/gfx-rs/gfx-extras/pull/5
**Testing**
Tested with examples from `wgpu-rs`.

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.
## TODO
- [x] wgpu-rs PR (https://github.com/gfx-rs/wgpu-rs/pull/380)

726: Basic support for minBufferBindingSize r=cwfitzgerald a=kvark
**Connections**
Has basic (partial) implementation of https://github.com/gpuweb/gpuweb/pull/678
wgpu-rs update - https://github.com/gfx-rs/wgpu-rs/pull/377
**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.
**Testing**
Tested on wgpu-rs examples
