Struct ShufflingAllocator 

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

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,

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

Allocates memory as described by the given layout.

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

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

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.

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

Shrinks or grows a block of memory to the given new_size in bytes. The block is described by the given ptr pointer and layout.
