pub struct MemoryPermit { /* private fields */ }
Expand description

A memory permit.

Implementations§

Source§

impl MemoryPermit

Source

pub fn num_bytes(&self) -> usize

Create a new memory permit from a list of permits.

Source

pub fn split( &mut self, mem_in_bytes: usize, ) -> Result<MemoryPermit, MemoryPermitError>

Split the memory permit into two.

§Panics

Panics if the number of bytes is greater than Self::num_bytes.

Source

pub async fn increase( &mut self, mem_in_bytes: usize, ) -> Result<(), MemoryPermitError>

Increase the memory permit by the given number of bytes.

Source

pub fn release(&mut self, mem_in_bytes: usize) -> Result<(), MemoryPermitError>

Partially release the memory permit.

This will release the memory permit by the given number of bytes.

§Panics

Panics if the number of bytes is greater than Self::num_bytes.
