IrBinding

Remarks

Slot is not the descriptor binding index. It numbers each kind separately, which is what the IR verifier checks for duplicates and what the IR dump prints; the (set, binding) pair a backend emits is assigned by Vixen.Raven.Reflection.BindingPlan, once, for every consumer.

Fields and properties (12)

• public IrVariable Variable
• public IrBindingKind Kind
• public int Slot
• public bool IsWritable

  Whether the shader may store into this binding. Only a RWBuffer or a storage image ever can.

• public ResourceSet Set

  The descriptor set this binding belongs to.

• public object? DefaultValue

  The initialiser the author wrote — var exposure: float = 1f — or null.

• public string? Semantic

  The pipeline semantic from [Semantic("…")], if any.

• public string Name

  The host-visible name: the variable's, unless this binding was contributed by a shader filling a compose slot, in which case it is qualified by that shader.

• public bool IsShared

  Whether this is one resource for the whole compilation rather than a contribution from each feature that declared it.

• public bool IsMaterialIndex

  Whether this is the index of the material record a draw reads.

• public bool IsDynamicOffset

  Whether this block is bound at an offset the host moves per draw — [DynamicOffset].

• public IrType Type

Methods (1)

• public IrBinding(IrVariable variable, IrBindingKind kind, int slot, string? semantic, ResourceSet set = PerMaterial, string? name = null, bool writable = false, object? defaultValue = null, bool shared = false, bool materialIndex = false, bool dynamicOffset = false)

  One resource a shader expects from the host. Slots are assigned per kind, in declaration order, so a host can bind against them deterministically.
