* replaced `.expect()` that provided no useful information with `.unwrap()`
* used `use` consistently (all types are `use`d all functions have the parent module `use`d)
* other formatting consistencies
Some drivers dont enforce a swapchain extent, so you need to check for
resize events from the os and then recreate the swapchain.
I took this opportunity to refactor the examples a bunch.
I want to do some more refactoring to make things consistent but I'll
leave that for a follow up PR.
There was a comment complaining that an AMD driver (which one? there are
three) was not setting the pResults.
I made this a non issue by replacing mem::uninitilized() with 0.
* vulkano_shaders_derive exposes a proc_macro instead of a proc_macro_derive
* move vulkano_shader out of vulkano_shaders_derive and deprecate vulkano_shaders_derive
* Update documentation
* Move vulkano_shader! to root of mod, so it works with rust 1.30
SPIR-V allows the array stride and size of a type to differ, but rust defines them to be the same. Thus
certain types when represented in rust will have the wrong layout. E.g. an array of vec3 can have an array
stride of 16 in SPIR-V, but an array of [f32;3] in rust would have a stride of 12. Thus using one for the
other would cause corruption.
This suggests a workaround by using a wrapping struct or upgrading the size of the type to one where the size
is the array stride.
I considered generating the wrapping struct for the user, but that seems very confusing for the user. We could
generate wrapping structs for all vec and mat types in arrays, but that would be a large API change.
See #298.
* Update PR template
* Rename queue to queue_family
* Add examples readme
* Use the same image output filename
* Move existing examples with multiple files into their own folder
* Improve error message when running runtime-shader in the wrong directory
Expand MissingUsage into MissingBufferUsage and MissingImageUsage
each with an enum so that the usage that is missing is obvious
in the error, e.g.:
thread 'main' panicked at 'add curimage: MissingImageUsage(Storage)'
