A primitive that appears in traces through transformations.

In JAX, when functions composed of primitives are traced, only the primitives appear in the trace. A HigherOrderPrimitive (HOP) can be bound to a function using call_bind, which traces the function and surfaces its Jaxpr in the trace in the HOP's params.

A HOP appears in the traces of transformed functions. Specifically, unlike jax.custom_transforms functions, which do not appear in a trace after a transformation like jax.grad or jax.vmap is applied, a HOP will create another HOP to appear in the trace after transformation, bound to the transformed function.
