Expand description

RAII guard for memory reservations.

Releases the reservation when dropped, unless committed.

Implementations§

Source§

impl<'a> ReservationGuard<'a>

Source

pub fn bytes(&self) -> u64

Returns the reserved bytes.

Source

pub fn commit(self)

Commits the reservation by recording it as an allocation.

The reservation is released and replaced with an actual allocation record.

Source

pub fn release(self)

Releases the reservation without allocating.
