Trait Implementations

impl<I: FragmentedBuffer, O: ReusableBuffer, A: BufferAlloc<O>> BufferProvider<I, O> for NoReuseBufferProvider<A>

type Error = <A as BufferAlloc<O>>::Error

The type of errors returned from reuse_or_realloc.

fn alloc_no_reuse( self, prefix: usize, body: usize, suffix: usize, ) -> Result<O, A::Error>

Attempts to produce an output buffer with the given constraints by allocating a new one.

fn reuse_or_realloc( self, buffer: I, prefix: usize, suffix: usize, ) -> Result<O, (A::Error, I)>

Consumes an input buffer and attempts to produce an output buffer with the given constraints, either by reusing the input buffer or by allocating a new one and copying the body into it.
