element_type_bytes()

size_t MayaFlux::Portal::Graphics::element_type_bytes ( GpuBufferBinding::ElementType  et )

noexcept

Byte width of one GpuBufferBinding::ElementType element.

Bridges to Kakshya::gpu_data_format_bytes for FLOAT32/UINT32/INT32, the single authoritative sizing source. Returns 0 for PASSTHROUGH, IMAGE_STORAGE, and IMAGE_SAMPLED, which carry no fixed element width.

Parameters

et	ElementType to size.

Returns

Byte width, or 0 if unsized.
