Struct shuffling_allocator::ShufflingAllocator

pub struct ShufflingAllocator<A> where
    A: 'static + GlobalAlloc,  { /* fields omitted */ }

A shuffling allocator.

Wraps an existing allocator and shuffles the order of heap allocations yielded.

See the crate-level documentation for more details.

Example

use shuffling_allocator::ShufflingAllocator;
use std::alloc::System;

static SHUFFLED_SYSTEM_ALLOC: ShufflingAllocator<System> = shuffling_allocator::wrap!(&System);

Trait Implementations

impl<A> GlobalAlloc for ShufflingAllocator<A> where
    A: GlobalAlloc, 

pub unsafe fn alloc(&self, layout: Layout) -> *mut u8

Allocate memory as described by the given layout.

pub unsafe fn dealloc(&self, ptr: *mut u8, layout: Layout)

Deallocate the block of memory at the given ptr pointer with the given layout.

pub unsafe fn alloc_zeroed(&self, layout: Layout) -> *mut u8

Behaves like alloc, but also ensures that the contents are set to zero before being returned.

pub unsafe fn realloc(
    &self,
    ptr: *mut u8,
    layout: Layout,
    new_size: usize
) -> *mut u8

Shrink or grow a block of memory to the given new_size. The block is described by the given ptr pointer and layout.
