Struct toolshed::CopyCell

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

This should be identical to the Cell implementation in the standard library, but always require that the internal type implements Copy and implements Copy itself.

Implementations

impl<T> CopyCell<T>

pub fn new(value: T) -> Self

Creates a new CopyCell containing the given value.

impl<T: Copy> CopyCell<T>

pub fn get(&self) -> T

Returns a copy of the contained value.

pub fn get_mut(&mut self) -> &mut T

Returns a mutable reference to the underlying data.

This call borrows CopyCell mutably, which gives us a compile time memory safety guarantee.

pub fn set(&self, value: T)

Sets the contained value.

Trait Implementations

impl<T: Copy> Clone for CopyCell<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Copy> Debug for CopyCell<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq<CopyCell<T>> for CopyCell<T>

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T: Copy> Copy for CopyCell<T>

impl<T: Eq> Eq for CopyCell<T>

impl<T> Send for CopyCell<T>

Sync is unsafe due to mutability, however Send is totally fine!
