Struct CallGuard 

pub struct CallGuard { /* private fields */ }

The owner’s handle on a guard: the guard ends its group when this handle goes away — by CallGuard::finish, by a drop, or by the owner’s death.

Implementations

impl CallGuard

pub fn finish(self) -> GuardOutcome

Lets go: the guard ends what is left of the group, and is reaped.

Trait Implementations

impl Drop for CallGuard

A handle that goes away without CallGuard::finish — an early return, an unwinding owner — still lets go of the guard and reaps it, so the group is ended and no guard process is left behind as a zombie.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
