In `wgpu_hal`: - Document that `wgpu_hal` guarantees that shaders will not access buffer contents beyond the bindgroups' bound regions, rounded up to some adapter-specific alignment. Introduce the term "accessible region" for the portion of the buffer that shaders can actually get at. - Document that all bets are off if you disable bounds checks with `ShaderModuleDescriptor::runtime_checks`. - Provide this alignment in `wgpu_hal::Alignments`. Update all backends appropriately. - In the Vulkan backend, use Naga to inject bounds checks on buffer accesses unless `robustBufferAccess2` is available; `robustBufferAccess` is not sufficient. Retrieve `VK_EXT_robustness2`'s properties, as needed to discover the alignment above. In `wgpu_core`: - Use buffer bindings' accessible regions to determine which parts of the buffer need to be initialized. In `wgpu_types`: - Document some of the possible effects of using `ShaderBoundsChecks::unchecked`. Fixes #1813. |
