This will make it easier for contributors to understand the file layout,
at the cost of said layout containing several more nested directories.
I will personally appreciate not having to remember to look for
`root.rs` instead of `main.rs`.
I also renamed the test targets so that they do not *all* share the
superfluous suffix “-test” (test targets live in a different namespace
than other target types and packages, so the name can presume that it
is always known that they are tests).
The Naga snapshot data sets `naga/tests/{in,out}` have been left in
their original positions.
This is a useful shortcut for tests and example code, allowing it to
create a noop device without needing to deal with nonexistent
fallibility and asynchrony.
This will help users determine whether the problem is:
* a backend is not statically enabled
* a backend is not dynamically enabled
* no drivers or physical adapters are present for that backend
(further distinction would be useful here)
* no adapters met the required criteria
There are deficiencies in the reporting of WebGPU vs. WebGL support.
Those would best be fixed by also fixing the mutual exclusion of those
backends.
This allows `wgpu` to not unconditionally depend on `std::path::Path`.
It’s also, in my opinion, more user-friendly, because the feature which
most users will not use (and is not currently functional) is now a
defaultable struct field instead of a required parameter.
The disadvantage is that `wgpu-types` now has to know about tracing.
Makes the dual source implementation in wgpu WebGPU spec compliant.
Furthermore, makes the dual source blending extension available when targeting WebGPU.
When the user provides values for a module's overrides, rather than
replacing override-sized array types with ordinary array types (which
could require adjusting type handles throughout the module), instead
edit all overrides to have initializers that are fully-evaluated
constant expressions. Then, change all backends to handle
override-sized arrays by retrieving their overrides' values.
For arrays whose sizes are override expressions, not simple references
to a specific override's value, let front ends built array types that
refer to anonymous overrides whose initializers are the necessary
expression.
This means that all arrays whose sizes are override expressions are
references to some `Override`. Remove `naga::PendingArraySize`, and
let `ArraySize::Pending` hold a `Handle<Override>` in all cases.
Expand `tests/gpu-tests/shader/array_size_overrides.rs` to include the
test case that motivated this approach.
