gpu_data_format_bytes()

MAYAFLUX_API size_t MayaFlux::Kakshya::gpu_data_format_bytes ( GpuDataFormat  fmt )

noexcept

Byte size of one element of a GpuDataFormat.

Single authoritative source for format sizing. Used by TextureAccess, ShaderSpec, and any other system that needs to derive byte counts from GpuDataFormat without duplicating the switch.

Parameters

fmt	GpuDataFormat value.

Returns

Byte size of one element, or 0 for unrecognised formats.
