FieldSymbol

Declared with val (or synthesized read-only) — assignable only in an initializer or constructor.

Declared const: a compile-time constant.

The folded value of a const field, when it could be computed.

Declared [Permutation]: a constant whose value the caller supplies per effect variant rather than the source fixing it.

A val type parameter — shader Blur<val TapCount: int> — rather than a field. Like a [Permutation] key it is a compile-time constant, but it has no default: a value is part of the shader's signature.

Declared compose: a protocol-typed slot filled by a concrete shader chosen when the shader is compiled.

Declared stream: per-invocation storage threaded between pipeline stages.

Declared groupshared: storage every invocation of one workgroup reaches and no other workgroup does.

The literal written in the declaration, or null when there is none.

The shader bound to this compose slot, or null when the field is not a slot or nothing valid is bound. Calls through the slot go straight to this type's members, so there is no dispatch at runtime.

How this field binds on the GPU when it is a shader member.

Whether this field becomes a descriptor binding — state the host supplies rather than storage the shader owns.

The descriptor set this field's binding belongs to, from a [PerFrame] / [PerView] / [PerMaterial] / [PerDraw] marker.

Whether this field is marked [PushConstant]: a small value the host writes into the command buffer rather than into a descriptor.

Whether this binding is one resource for the whole compilation rather than a contribution from each feature that declares it — [Shared].

Whether this field is the index of the material record a draw reads — [MaterialIndex].

The texel format from [Format("…")], resolved. Null unless this field is a storage image with a recognised format.

The pipeline semantic from a [Semantic("…")] attribute, or null.
