Methods

impl<'a> AddrSpace<'a>

pub const unsafe fn from_raw(ptr: *mut u8, size: usize) -> AddrSpace<'a>

pub fn size(&self) -> usize

Returns the total number of bytes in this address space.

pub fn live(&self) -> usize

Returns the number of live allocations from this address space.

pub fn used(&self) -> usize

Trait Implementations

impl<'a> Heap<'a> for AddrSpace<'a>

unsafe fn alloc(&self, layout: Layout) -> Result<Block<'a>, HeapError>

Allocates a new memory block sized and aligned to at least Layout; returns None if the allocation fails.

unsafe fn dealloc(&self, block: Block<'a>) -> usize

Deallocates a memory block previously allocated by alloc. Returns the number of freed bytes.

impl<'a> Drop for AddrSpace<'a>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a> Sync for AddrSpace<'a>

impl<'a> Send for AddrSpace<'a>

impl<'a> Clone for AddrSpace<'a>

fn clone(&self) -> AddrSpace<'a>

Returns a copy of the value.

default fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
