Struct MspaceAlloc 

pub struct MspaceAlloc { /* private fields */ }

MspaceAlloc allocator

This allocator allows you to use a initial capacity bigger than the default granularity.

Implementations

impl MspaceAlloc

pub const fn new(capacity: usize) -> Self

new method

Initialize MspaceAlloc object. Use this method to initialize a static variable annotated as the global allocator.

pub unsafe fn destroy(&self)

destroy method

Destroys MspaceAlloc object. All mmaped pages will be released.

Safety

You must ensure all allocated objects (Vec, Box, etc.) are dropped before destroying the allocator!

Trait Implementations

impl GlobalAlloc for MspaceAlloc

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 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.

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.
