Function Documentation

finally()

template<typename Func >

static auto eagine::finally ( Func  func ) -> func_on_scope_exit<Func>

inlinestatic

Function constructing on-scope-exit actions.

This function takes the specified callable argument and creates an object which when destroyed, typically when leaving scope block, invokes the callable.
