Struct RetainedMemory 

pub struct RetainedMemory { /* private fields */ }

Implementations

impl RetainedMemory

pub fn bytes(&self) -> usize

Total admitted bytes, including any private owner allowance.

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

Admits an absolute total high-water mark; this never shrinks the claim. Concurrent incremental allocators must use try_grow_by.

pub fn try_grow_by(&self, additional: usize) -> Result<()>

Atomically admits an additional allocation peak without waiting.

Refusal leaves the claim unchanged. Use this for independent increments through aliases; bytes() + try_grow_to() is not an atomic increment.
