Struct Stash

pub struct Stash {
    buffers: UnsafeCell<Vec<Vec<u8>>>,
    mmaps: UnsafeCell<Vec<Mmap>>,
}

A simple arena allocator for byte buffers.

Fields

buffers: UnsafeCell<Vec<Vec<u8>>>

mmaps: UnsafeCell<Vec<Mmap>>

Implementations

impl Stash

pub fn new() -> Stash

pub fn allocate(&self, size: usize) -> &mut [u8]

Allocates a buffer of the specified size and returns a mutable reference to it.

pub fn cache_mmap(&self, map: Mmap) -> &[u8]

Stores a Mmap for the lifetime of this Stash, returning a pointer which is scoped to just this lifetime.
