Functions
bool	RhiValidateComputeBindGroupLayout (const RHI_BIND_GROUP_LAYOUT_DESC &aLayout)
	Validate a compute bind group layout.
bool	RhiValidateComputePipelineDesc (const RHI_COMPUTE_PIPELINE_DESC &aDesc)
	Validate the portable contract without accessing a GPU or inspecting shader bytecode.
bool	RhiValidateComputeJob (const RHI_COMPUTE_JOB &aJob, const RHI_COMPUTE_DEVICE_LIMITS &aLimits, const RHI_COMPUTE_JOB_LOOKUP &aLookup)
	Check a whole job against live resources before any of it executes, so a bad job has no partial effect.

RhiValidateComputeBindGroupLayout()

bool RhiValidateComputeBindGroupLayout

(

const RHI_BIND_GROUP_LAYOUT_DESC &

aLayout

)

Validate a compute bind group layout.

Every entry must be visible to compute and no buffer may use binding 0, which Metal reserves for push constants.

RhiValidateComputeJob()

bool RhiValidateComputeJob	(	const RHI_COMPUTE_JOB &	aJob,
		const RHI_COMPUTE_DEVICE_LIMITS &	aLimits,
		const RHI_COMPUTE_JOB_LOOKUP &	aLookup )

Check a whole job against live resources before any of it executes, so a bad job has no partial effect.

Push constants must be pushed in full after each Bind() and before the next Dispatch().
