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.

Safety

You must ensure all allocated objects 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.
