Struct Deferred

Source 
pub struct Deferred<F: FnOnce()>(/* private fields */);
Expand description

Defers execution of a closure until a scope is exited.

As seen in “The Go Programming Language”.

Implementations§

Source§

impl<F: FnOnce()> Deferred<F>

Source

pub const fn new(f: F) -> Self

Defer execution of f until this scope is exited.

Source

pub fn cancel(&mut self)

Cancel the deferred execution.of the closure passed to defer.

Calling this method will prevent the closure from being executed when this Deferred guard is dropped.
