Fields

buffer_copy_offset: NonZero<u64>

The alignment of the start of the buffer used as a GPU copy source.

buffer_copy_pitch: NonZero<u64>

The alignment of the row pitch of the texture data stored in a buffer that is used in a GPU copy operation.

uniform_bounds_check_alignment: NonZero<u64>

The finest alignment of bound range checking for uniform buffers.

When wgpu_hal restricts shader references to the accessible region of a Uniform buffer, the size of the accessible region is the bind group binding’s stated size, rounded up to the next multiple of this value.

We don’t need an analogous field for storage buffer bindings, because all our backends promise to enforce the size at least to a four-byte alignment, and wgpu_hal requires bound range lengths to be a multiple of four anyway.

raw_tlas_instance_size: usize

The size of the raw TLAS instance

ray_tracing_scratch_buffer_alignment: u32

What the scratch buffer for building an acceleration structure must be aligned to
