Struct MoveCell

pub struct MoveCell<T>(/* private fields */);

A container similar to std::cell::Cell, but that also supports not-implicitly-copyable types.

Implementations

impl<T> MoveCell<T>

pub fn new(value: T) -> MoveCell<T>

Create a new MoveCell containing the given value.

pub fn into_inner(self) -> T

Consume the MoveCell and return the inner value.

pub fn replace(&self, new_value: T) -> T

Return the inner value after replacing it with the given value.

pub unsafe fn as_unsafe_cell(&self) -> &UnsafeCell<T>

Returns a reference to the underlying UnsafeCell.

Unsafety

This method is unsafe because UnsafeCell’s field is public.

impl<T: Default> MoveCell<T>

Convenience methods for when there is a default value.

pub fn take(&self) -> T

Return the inner value after replacing it with the default value.

pub fn borrow(&self) -> Borrow<'_, T>

Take the value, and return it in a Borrow guard that will return it when dropped. The cell’s contents are set to the default value until the guard is dropped.

Trait Implementations

impl<T: Default + Clone> Clone for MoveCell<T>

The cell’s contents are temporarily set to the default value during the clone.

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Default + Debug> Debug for MoveCell<T>

The cell’s contents are temporarily set to the default value during the formatting.

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

Formats the value using the given formatter.

impl<T: Default> Default for MoveCell<T>

fn default() -> MoveCell<T>

Returns the “default value” for a type.

impl<T: Default + PartialEq> PartialEq for MoveCell<T>

The cell’s contents are temporarily set to the default value during the comparaison.

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

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

fn ne(&self, other: &MoveCell<T>) -> bool

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

impl<T: Default + Eq> Eq for MoveCell<T>

The cell’s contents are temporarily set to the default value during the comparaison.
