Crate scoped

Expand description

This crate provides little utilities to declare callbacks inside a scope, that get executed on success, failure, or exit on that scope.

This is different than the ScopeGuard crate does, because here it’s dependent on the scope’s outcome which callbacks should run.

Structs

A guard is a handle to schedule callbacks on, from an outer scope.

A trait to annotate whether a type is success or failure.

Executes the scope scope. A scope is a closure, in which access to a guard is granted. A guard is used to schedule callbacks to run on a scope’s success, failure, or exit, using Guard::on_scope_success, Guard::on_scope_failure, Guard::on_scope_exit.
