Struct PhaseGuard 

pub struct PhaseGuard { /* private fields */ }

RAII guard for one occurrence of a named background phase. Increments the phase’s count on creation (see register_active_phase); decrements on Drop, so the count comes back down whether the guarded work returns normally, panics, or is cancelled — the same rationale as BackgroundTaskGuard above.

Trait Implementations

impl Drop for PhaseGuard

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.
