Trait Implementations

impl<'a, C: AsBytes<'a>> AsBytes<'a> for Boxed<C>

fn as_bytes(&self) -> impl Iterator<Item = (u64, &'a [u8])>

Presents self as a sequence of byte slices, with their required alignment.

impl<C: Clear> Clear for Boxed<C>

fn clear(&mut self)

Clears self, without changing its capacity.

impl<T: Clone> Clone for Boxed<T>

fn clone(&self) -> Boxed<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<C: Container> Container for Boxed<C>

type Ref<'a> = Boxed<<C as Container>::Ref<'a>>

For each lifetime, a reference with that lifetime.

type Borrowed<'a> = Boxed<<C as Container>::Borrowed<'a>>

The type of a borrowed container.

fn borrow<'a>(&'a self) -> Self::Borrowed<'a>

Converts a reference to the type to a borrowed variant.

fn reborrow<'b, 'a: 'b>(item: Self::Borrowed<'a>) -> Self::Borrowed<'b>

where Self: 'a,

Reborrows the borrowed type to a shorter lifetime. See Columnar::reborrow for details.

fn reborrow_ref<'b, 'a: 'b>(item: Self::Ref<'a>) -> Self::Ref<'b>

where Self: 'a,

Reborrows the borrowed type to a shorter lifetime. See Columnar::reborrow for details.

fn extend_from_self(&mut self, other: Self::Borrowed<'_>, range: Range<usize>)

Extends self by a range in other.

fn reserve_for<'a, I>(&mut self, selves: I)

where Self: 'a, I: Iterator<Item = Self::Borrowed<'a>> + Clone,

fn with_capacity_for<'a, I>(selves: I) -> Self

where Self: 'a, I: Iterator<Item = Self::Borrowed<'a>> + Clone,

Allocates an empty container that can be extended by selves without reallocation.

impl<T: Default> Default for Boxed<T>

fn default() -> Boxed<T>

Returns the “default value” for a type.

impl<T> Deref for Boxed<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T> DerefMut for Boxed<T>

Reconstructs self from a sequence of correctly aligned and sized bytes slices.

impl<C: HeapSize> HeapSize for Boxed<C>

fn heap_size(&self) -> (usize, usize)

Active (len) and allocated (cap) heap sizes in bytes. This should not include the size of self itself.
