Struct MaybeBox 

pub struct MaybeBox<T> { /* private fields */ }

Box-like type providing opportunistic heap allocation when the alloc feature is available that falls back to stack allocation when it’s unavailable.

Implementations

impl<T> MaybeBox<T>

pub fn new(inner: T) -> Self

Create a new MaybeBox, using Box if alloc is available.

pub fn into_inner(self) -> T

Move the contents out of a MaybeBox.

This emulates the compiler magic that allows moving out of a box with *my_box.

Trait Implementations

impl<T: Clone> Clone for MaybeBox<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for MaybeBox<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Deref for MaybeBox<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for MaybeBox<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T: PartialEq> PartialEq for MaybeBox<T>

fn eq(&self, other: &MaybeBox<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
