Struct CountdownGuard

Source 
pub struct CountdownGuard<'a> { /* private fields */ }
Expand description

An opaque guard struct that decrements the count of a borrowed CountdownEvent on drop.

See CountdownEvent::guard for more information about this struct.

Trait Implementations§

Source§

impl<'a> Drop for CountdownGuard<'a>

Upon drop, this guard will decrement the counter of its parent CountdownEvent. If this would cause an error (see CountdownEvent::signal for details), the error is silently ignored.

fn drop(&mut self)

Executes the destructor for this type. Read more
