Function wgpu_core::command::transfer::validate_texture_copy_range

pub(crate) fn validate_texture_copy_range<T>(
    texture_copy_view: &ImageCopyTexture<T>,
    desc: &TextureDescriptor<(), Vec<TextureFormat>>,
    texture_side: CopySide,

WebGPU’s validating texture copy range algorithm.

Copied with minor modifications from WebGPU standard.

Returns the HAL copy extent and the layer count.
