Struct mycelium_alloc::bump::Alloc

pub struct Alloc<const SIZE: usize> { /* private fields */ }

Implementations

impl<const SIZE: usize> Alloc<SIZE>

pub const fn new() -> Self

pub fn total_size(&self) -> usize

pub fn allocated_size(&self) -> usize

pub fn owns(&self, addr: *mut u8) -> bool

Trait Implementations

impl<const SIZE: usize> Debug for Alloc<SIZE>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<const SIZE: usize> GlobalAlloc for Alloc<SIZE>

unsafe fn alloc(&self, layout: Layout) -> *mut u8

Safety

See GlobalAlloc::alloc

NOTABLE INVARIANTS:

• Layout is non-zero sized (enforced by GlobalAlloc)
• align is a power of two (enforced by Layout::from_size_align)

unsafe fn dealloc(&self, _ptr: *mut u8, _layout: Layout)

Does nothing, because freeing is hard.

Safety

See GlobalAlloc::dealloc

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.
