pub struct MemorySlicerGuard<'a> { /* private fields */ }

Implementations

impl MemorySlicerGuard<'_>

pub fn range(&self) -> MemorySlicerRange

pub fn total(&self) -> ByteSize

pub fn available(&self) -> ByteSize

pub fn snapshot(&self) -> MemorySlicer

pub fn alloc_fixed(&mut self, bytes: ByteSize) -> bool

pub fn alloc_ratio(&mut self, nom: usize, denom: usize) -> Option<ByteSize>

pub fn alloc_in_range<R: RangeBounds<ByteSize>>( &mut self, bytes: R, ) -> Option<ByteSize>

pub fn alloc_constraints<C: MemoryConstraints>( &mut self, constraints: C, ) -> Result<C::Output, ByteSize>

Tries to allocate an amount of memory which satisfies provided constraints.

On success returns allocated amounts in the same order as constraints. Otherwise returns the minimum required memory size (total).

pub fn overflowing_alloc_constraints<C: MemoryConstraints>( &mut self, constraints: C, ) -> AllocatedMemoryConstraints<C::Output>

Tries to allocate an amount of memory which satisfies provided constraints.

In case of overflow still allocates, but returns the required remainder in AllocatedMemoryConstraints::overflow.

pub fn subdivide(&mut self, bytes: ByteSize) -> Option<MemorySlicer>

pub fn subdivide_ratio( &mut self, nom: usize, denom: usize, ) -> Option<MemorySlicer>

pub fn subdivide_in_range<R: RangeBounds<ByteSize>>( &mut self, bytes: R, ) -> Option<MemorySlicer>
