Struct EmbeddedAllocator 

pub struct EmbeddedAllocator<const SIZE: usize, const POOL_SIZE: usize> { /* private fields */ }

Global embedded allocator combining bump and pool allocation

For no_std environments, this can be used as the global allocator.

Implementations

impl<const SIZE: usize, const POOL_SIZE: usize> EmbeddedAllocator<SIZE, POOL_SIZE>

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

Create a new embedded allocator

Arguments

• block_size - Size of blocks in the pool allocator

pub unsafe fn reset(&self)

Reset both allocators

Safety

Only call when no outstanding allocations exist.

pub fn used(&self) -> usize

Get total memory used

pub const fn capacity(&self) -> usize

Get total capacity

Trait Implementations

impl<const SIZE: usize, const POOL_SIZE: usize> GlobalAlloc for EmbeddedAllocator<SIZE, POOL_SIZE>

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 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

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.
