Struct glsp_engine::RFn

pub struct RFn(_);

The rfn primitive type.

Rust functions are represented by a small Copy type (a 32-bit integer id).

Most of this type's methods belong to the callable abstract type, so they can be found in the CallableOps trait. To invoke an RFn, use glsp::call.

To convert a function pointer or a closure into an RFn, you should usually call glsp::bind_rfn or glsp::rfn.
