class ShaderProgram

Defined at line 30 of file ../../src/ui/lib/escher/vk/shader_program.h

ShaderProgram encapsulates a set of ShaderModules, which are used to generate

vk::Pipelines. This is done in collaboration with CommandBuffer; different

pipelines may be required depending on the current CommandBuffer state.

ShaderProgram listens for changes in the ShaderModules; whenever new SPIR-V

is available, all existing pipelines are invalidated and will be lazily

regenerated upon demand.

PipelineLayoutPtr ObtainPipelineLayout (impl::PipelineLayoutCache * pipeline_layout_cache, const SamplerPtr & immutable_sampler)

Return the pipeline layout for this program, operating with the optional

immutable sampler passed in (pass the null vk::Sampler handle to opt-out).

TODO(https://fxbug.dev/42152423): This code-flow assumes that ShaderPrograms source from, at

most, a single sampler. This is a blocking bug for implementing, e.g.,

https://fxbug.dev/42151968.
