Struct mini_alloc::MiniAlloc

pub struct MiniAlloc<'a> { /* private fields */ }

A wee allocator.

Safety

When used in unix environments, cannot move in memory. Typically not an issue if you’re just using this as a static global allocator.

Implementations

impl<'a> WeeAlloc<'a>

pub const INIT: WeeAlloc<'a> = <Self as ConstInit>::INIT

An initial const default construction of a WeeAlloc allocator.

This is usable for initializing statics that get set as the global allocator.

Trait Implementations

impl GlobalAlloc for WeeAlloc<'static>

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

Allocate memory as described by the given layout.

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

Deallocate 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

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