cowboy_handler:terminate(3)

Name

cowboy_handler:terminate - Terminate the handler

terminate(Reason, PartialReq, State, Handler) -> ok

Reason     :: any()
PartialReq :: map()
State      :: any()
Handler    :: module()

Call the optional terminate callback if it is defined.

Make sure to use this function at the end of the execution of modules that implement custom handler behaviors.

Reason: Reason for termination.
PartialReq: The Req object.

It is possible to remove fields from the Req object to save memory when the handler has no concept of requests/responses. The only requirement is that a map is provided.
State: Handler state.
Handler: Handler module.

The atom ok is always returned. It can be safely ignored.

Terminate a handler normally

cowboy_handler:terminate(normal, Req, State, Handler).
