IrStream

Remarks

Deliberately not an IrBinding. A binding is host-visible state with a descriptor; a stream is per-invocation and lives in the pipeline's own interface, so nothing about it reaches BindingPlan or the descriptor sets.

The variable it carries is a module-scope global, which is exactly how both targets model a stage interface — a SPIR-V Input/Output variable and a GLSL in/out are both module scope. So a read lowers to an ordinary load and a write to an ordinary store, and it is the direction that the backend resolves per stage. Which direction a stage needs is not declared: see StreamInputs.

Fields and properties (4)

• public IrVariable Variable
• public string Name
• public IrType Type
• public InterpolationMode Interpolation

  How the rasteriser interpolates it, from [Interpolation("…")] on the stream declaration.

Methods (2)

• public IrStream(IrVariable variable, InterpolationMode interpolation = Smooth)

  An interstage value the shader declares with stream: written by one stage, read by the next.

• public override string ToString()
