Struct MemoryReservation 

pub struct MemoryReservation { /* private fields */ }

A unique lease: release it only after the associated allocation has been freed.

Implementations

impl MemoryReservation

pub fn bytes(&self) -> usize

pub fn budget(&self) -> &MemoryBudget

pub fn split(&mut self, bytes: usize) -> Self

Transfer part of an existing allocation lease without releasing or reserving bytes.

Panics if bytes exceeds this lease. The original lease is unchanged on failure.

pub fn grow(&mut self, additional: usize) -> Result<(), MemoryError>

Reserve additional bytes atomically; a failed request leaves this lease unchanged.

pub fn absorb(&mut self, other: Self)

Transfer ownership without releasing and reacquiring the shared allowance.

Panics if the leases belong to different allowances.

Trait Implementations

impl Debug for MemoryReservation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for MemoryReservation

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.
