Struct Stacked

pub struct Stacked { /* private fields */ }

Implementations

impl Stacked

pub const fn from_static_slice(buf: &'static mut [MaybeUninit<u8>]) -> Self

pub const fn from_static_array<const BUF_LEN: usize>( buf: &'static mut [MaybeUninit<u8>; BUF_LEN], ) -> Self

pub unsafe fn with_buf_raw<T>( buf_ptr: NonNull<MaybeUninit<u8>>, buf_len: usize, f: impl for<'a> FnOnce(&'a Stacked) -> T, ) -> T

Safety

buf_ptr should be a valid unique pointer to a slice with params.buf_len() bytes length.

Arguments should satisfy buf_len <= isize::MAX as usize, and (isize::MAX as usize) - buf_len >= buf_ptr as usize

Trait Implementations

impl Allocator for Stacked

fn allocate(&self, layout: Layout) -> Result<NonNull<[u8]>, AllocError>

🔬This is a nightly-only experimental API. (allocator_api)

Attempts to allocate a block of memory.

unsafe fn deallocate(&self, ptr: NonNull<u8>, layout: Layout)

🔬This is a nightly-only experimental API. (allocator_api)

Deallocates the memory referenced by ptr.

unsafe fn grow( &self, ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

🔬This is a nightly-only experimental API. (allocator_api)

Attempts to extend the memory block.

unsafe fn grow_zeroed( &self, ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

🔬This is a nightly-only experimental API. (allocator_api)

Behaves like grow, but also ensures that the new contents are set to zero before being returned.

unsafe fn shrink( &self, ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

🔬This is a nightly-only experimental API. (allocator_api)

Attempts to shrink the memory block.

fn allocate_zeroed(&self, layout: Layout) -> Result<NonNull<[u8]>, AllocError>

🔬This is a nightly-only experimental API. (allocator_api)

Behaves like allocate, but also ensures that the returned memory is zero-initialized.

fn by_ref(&self) -> &Self

where Self: Sized,

🔬This is a nightly-only experimental API. (allocator_api)

Creates a “by reference” adapter for this instance of Allocator.

impl Drop for Stacked

fn drop(&mut self)

Executes the destructor for this type.

impl Fallbackable for Stacked

unsafe fn has_allocated(&self, ptr: NonNull<u8>, _layout: Layout) -> bool

Safety

fn allows_fallback(&self, _layout: Layout) -> bool

impl NonUnwinding for Stacked
