Struct moveit::stackbox::Slot[−][src]

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>[src]

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

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) -> StackBox<'frame, T>[src]

Put val into this slot, returning a new StackBox.

The stackbox! macro is a shorthand for this function.

pub fn pin(self, val: T) -> Pin<StackBox<'frame, T>>[src]

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

pub fn emplace<C: Ctor<Output = T>>(self, ctor: C) -> Pin<StackBox<'frame, T>>[src]

Emplace ctor into this slot, returning a new, pinned StackBox.

The emplace! macro is a shorthand for this function.

pub fn try_emplace<C: TryCtor<Output = T>>(
    self,
    ctor: C
) -> Result<Pin<StackBox<'frame, T>>, C::Error>[src]

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