Fields§

§available_stages: ShaderStages

Set of shader stages where calling this function is valid.

§uniformity: Uniformity

Uniformity characteristics.

§may_kill: bool

Function may kill the invocation.

§sampling_set: FastHashSet<SamplingKey>

All pairs of (texture, sampler) globals that may be used together in sampling operations by this function and its callees. This includes pairings that arise when this function passes textures and samplers as arguments to its callees.

This table does not include uses of textures and samplers passed as arguments to this function itself, since we do not know which globals those will be. However, this table is exhaustive when computed for an entry point function: entry points never receive textures or samplers as arguments, so all an entry point’s sampling can be reported in terms of globals.

The GLSL back end uses this table to construct reflection info that clients need to construct texture-combined sampler values.

§dual_source_blending: bool

Indicates that the function is using dual source blending.
