Implementations

impl MipsMcuHeap

pub const fn empty() -> MipsMcuHeap

Crate a new UNINITIALIZED heap allocator

You must initialize this heap using the init method before using the allocator.

pub fn init(&self)

Initialize heap with heap start location from linker and a defined initial size

pub fn used(&self) -> usize

Returns an estimate of the amount of bytes in use.

pub fn free(&self) -> usize

Returns an estimate of the amount of bytes available.

pub fn bottom(&self) -> *mut u8

Returns the start (bottom) of the heap

pub fn top(&self) -> *mut u8

Returns the end (top) of the heap

Trait Implementations

impl GlobalAlloc for MipsMcuHeap

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.
