id<T extends Function> function

T id<T extends Function>(
  1. dynamic id,
  2. T fn
)

A special function that can be wrapped around another function in order to tell nyxx_commands how to identify the function at compile time.

This function is used to identify a callback function so that compiled nyxx_commands can extract the type & annotation data for that function.

It is a compile-time error for two id invocations to share the same id parameter. It is a runtime error in compiled nyxx_commands to create a ChatCommand with a non-wrapped function.

Implementation

T id<T extends Function>(dynamic id, T fn) {
  idMap[fn] = id;

  return fn;
}
