This reference lists the public declarations for this part of the library. See Reading API signatures for parameter and result notation. Shader-only declarations can be used only inside @compute, @vertex, @fragment, inferred helpers and ray tracing shader functions; using them elsewhere is a compile error.

ClosestHitAttribute

Marks a closest-hit shader, which runs once for the nearest surface a ray hit. Its first parameter is ref to the ray's payload struct, which it fills in; its second receives the hit's attributes, such as GpuTriangleHit for triangle geometry. Use it in a GpuHitGroup.
