Trait ComputeAllocator

pub trait ComputeAllocator<F, Mem: ComputeMemory<F>> {
    // Required methods
    fn alloc(&self, n: usize) -> Result<Mem::FSliceMut<'_>, Error>;
    fn capacity(&self) -> usize;
    fn subscope_allocator(&mut self) -> impl ComputeAllocator<F, Mem>;
}

Required Methods

fn alloc(&self, n: usize) -> Result<Mem::FSliceMut<'_>, Error>

Allocates a slice of elements.

This method operates on an immutable self reference so that multiple allocator references can co-exist. This follows how the bumpalo crate’s Bump interface works. It may not be necessary actually (since this partitions a borrowed slice, whereas Bump owns its memory).

Pre-conditions

• n must be a multiple of Mem::ALIGNMENT

fn capacity(&self) -> usize

Returns the remaining number of elements that can be allocated.

fn subscope_allocator(&mut self) -> impl ComputeAllocator<F, Mem>

Returns the remaining unallocated capacity as a new allocator with a limited scope.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
