Struct UnpodStack 

pub struct UnpodStack<'a> { /* private fields */ }

Owns an unsized array of data, allocated from some stack.

Methods from Deref<Target = MemStack>

pub fn can_hold(&self, alloc_req: StackReq) -> bool

Returns true if the stack can hold an allocation with the given size and alignment requirements.

pub fn len_bytes(&self) -> usize

Returns the number of bytes that this stack can hold.

pub fn as_ptr(&self) -> *const u8

Returns a pointer to the (possibly uninitialized) stack memory.

pub fn make_aligned_uninit<T>( &mut self, size: usize, align: usize, ) -> (&mut [MaybeUninit<T>], &mut MemStack)

Returns a new aligned and uninitialized DynArray and a stack over the remainder of the buffer.

Panics

Panics if the stack isn’t large enough to allocate the array.

pub fn make_aligned_with<T>( &mut self, size: usize, align: usize, f: impl FnMut(usize) -> T, ) -> (DynArray<'_, T>, &mut MemStack)

Returns a new aligned DynArray, initialized with the provided function, and a stack over the remainder of the buffer.

Panics

Panics if the stack isn’t large enough to allocate the array, or if the provided function panics.

pub fn make_uninit<T>( &mut self, size: usize, ) -> (&mut [MaybeUninit<T>], &mut MemStack)

Returns a new uninitialized DynArray and a stack over the remainder of the buffer.

Panics

Panics if the stack isn’t large enough to allocate the array.

pub fn make_with<T>( &mut self, size: usize, f: impl FnMut(usize) -> T, ) -> (DynArray<'_, T>, &mut MemStack)

Returns a new DynArray, initialized with the provided function, and a stack over the remainder of the buffer.

Panics

Panics if the stack isn’t large enough to allocate the array, or if the provided function panics.

pub fn collect_aligned<I>( &mut self, align: usize, iter: impl IntoIterator<Item = I>, ) -> (DynArray<'_, I>, &mut MemStack)

Returns a new aligned DynArray, initialized with the provided iterator, and a stack over the remainder of the buffer.
If there isn’t enough space for all the iterator items, then the returned array only contains the first elements that fit into the stack.

Panics

Panics if the provided iterator panics.

pub fn collect<I>( &mut self, iter: impl IntoIterator<Item = I>, ) -> (DynArray<'_, I>, &mut MemStack)

Returns a new DynArray, initialized with the provided iterator, and a stack over the remainder of the buffer.
If there isn’t enough space for all the iterator items, then the returned array only contains the first elements that fit into the stack.

Panics

Panics if the provided iterator panics.

pub fn bump<'bump, 'stack>( self: &'bump mut &'stack mut MemStack, ) -> &'bump mut Bump<'stack>

Trait Implementations

impl Deref for UnpodStack<'_>

type Target = MemStack

The resulting type after dereferencing.

fn deref(&self) -> &<UnpodStack<'_> as Deref>::Target

Dereferences the value.

impl DerefMut for UnpodStack<'_>

fn deref_mut(&mut self) -> &mut <UnpodStack<'_> as Deref>::Target

Mutably dereferences the value.

impl Drop for UnpodStack<'_>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
