Struct scoped_allocator::Place

pub struct Place<'a, T: 'a, A: 'a + Allocator> { /* fields omitted */ }

A place for allocating into. This is only used for in-place allocation, e.g. let val = in (alloc.allocate().unwrap())

Trait Implementations

impl<'a, T: 'a, A: 'a + Allocator> Placer<T> for Place<'a, T, A>

type Place = Self

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

Place is the intermedate agent guarding the uninitialized state for Data.

fn make_place(self) -> Self

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

Creates a fresh place from self.

impl<'a, T: 'a, A: 'a + Allocator> InPlace<T> for Place<'a, T, A>

type Owner = Allocated<'a, T, A>

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

Owner is the type of the end value of PLACE <- EXPR

unsafe fn finalize(self) -> Self::Owner

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

Converts self into the final value, shifting deallocation/cleanup responsibilities (if any remain), over to the returned instance of Owner and forgetting self.

impl<'a, T: 'a, A: 'a + Allocator> StdPlace<T> for Place<'a, T, A>

fn pointer(&mut self) -> *mut T

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

Returns the address where the input value will be written. Note that the data at this address is generally uninitialized, and thus one should use ptr::write for initializing it.

impl<'a, T: 'a, A: 'a + Allocator> Drop for Place<'a, T, A>

fn drop(&mut self)

A method called when the value goes out of scope.
