Struct moveit::slot::Slot

pub struct Slot<'frame, T>(_);

An empty slot on the stack into which a value could be emplaced.

The 'frame lifetime refers to the lifetime of the stack frame this Slot’s storage is allocated on.

See slot!().

Implementations

impl<'frame, T> Slot<'frame, T>

pub unsafe fn new_unchecked(ptr: &'frame mut MaybeUninit<T>) -> Self

Creates a new Slot with the given pointer as its basis.

To safely construct a Slot, use slot!().

Safety

ptr must not be outlived by any other pointers to its allocation.

pub fn put(self, val: T) -> MoveRef<'frame, T>

Put val into this slot, returning a new MoveRef.

pub fn pin(self, val: T) -> Pin<MoveRef<'frame, T>>

Pin val into this slot, returning a new, pinned MoveRef.

pub fn emplace<N: New<Output = T>>(self, new: N) -> Pin<MoveRef<'frame, T>>

Emplace new into this slot, returning a new, pinned MoveRef.

pub fn try_emplace<N: TryNew<Output = T>>(
    self,
    new: N
) -> Result<Pin<MoveRef<'frame, T>>, N::Error>

Try to emplace new into this slot, returning a new, pinned MoveRef.
