Struct AlignedDestination 

pub struct AlignedDestination(/* private fields */);

What SystemDestinations hands out: one host allocation at the declared alignment.

A named type because DestinationAlloc::Dest is part of the public API; the allocation itself stays an implementation detail.

Examples

use hurray_io::stream::{Destination, DestinationAlloc, DestinationRequest, SystemDestinations};

let mut dest = SystemDestinations
    .allocate(DestinationRequest { index: 0, byte_size: 32, alignment: 128 })?;
dest.as_mut_slice().fill(0xAB);
let frozen = dest.freeze();
assert_eq!(frozen.len(), 32);
assert_eq!(frozen.as_ptr() as usize % 128, 0);

Trait Implementations

impl Destination for AlignedDestination

fn as_mut_slice(&mut self) -> &mut [u8]

The bytes to fill, exactly byte_size long.

fn freeze(self) -> Bytes

Hands the filled memory out as [Bytes], without copying it.
