gleamunison/cancellation

A single-use cancellation flag shared by caller and transport. No server, registry, or background job is needed to cancel an outstanding request.

Types

Token

opaque </>

Holds the Erlang atomics reference. The constructor is used here, so the type is a real value the FFI returns into rather than a name it pretends to produce; the reference never escapes the module.
