Struct SystemDestinations 

pub struct SystemDestinations;

The default allocator: one host allocation per buffer at the declared alignment.

Examples

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

let mut dest = SystemDestinations
    .allocate(DestinationRequest { index: 0, byte_size: 64, alignment: 64 })?;
assert_eq!(dest.as_mut_slice().len(), 64);
assert_eq!(dest.as_mut_slice().as_ptr() as usize % 64, 0);
