Struct QueryMemoryLease 

pub struct QueryMemoryLease { /* private fields */ }

Implementations

impl QueryMemoryLease

pub fn bytes(&self) -> usize

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

pub fn shrink(&mut self, bytes: usize)

pub fn reset(&mut self)

Trait Implementations

impl Debug for QueryMemoryLease

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

Formats the value using the given formatter.

impl Drop for QueryMemoryLease

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.

impl GraphReadAllocation for QueryMemoryLease

fn bytes(&self) -> usize

fn grow(&mut self, bytes: usize) -> Result<()>

Reserve additional bytes atomically before allocation. Refusal leaves the existing reservation intact.

fn retain_state(&mut self) -> Result<(), HawDBError>

Move an admitted read into retained operator state before insertion. Query allocators may atomically transfer to a separately bounded state account. Standalone allocators retain their existing explicit policy.
