Struct freya::prelude::RefCell

pub struct RefCell<T>where
    T: ?Sized,{ /* private fields */ }

A clone of the standard library’s RefCell type.

Implementations

impl<T> RefCell<T>

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

Creates a new RefCell containing value.

pub fn into_inner(self) -> T

Consumes the RefCell, returning the wrapped value.

impl<T> RefCell<T>where T: ?Sized,

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

Immutably borrows the wrapped value.

The borrow lasts until the returned Ref exits scope. Multiple immutable borrows can be taken out at the same time.

Panics

Panics if the value is currently mutably borrowed.

pub fn try_borrow(&self) -> Result<Ref<'_, T>, BorrowError>

Immutably borrows the wrapped value.

The borrow lasts until the returned Ref exits scope. Multiple immutable borrows can be taken out at the same time.

Panics

Panics if the value is currently mutably borrowed.

pub fn borrow_mut(&self) -> RefMut<'_, T>

Mutably borrows the wrapped value.

The borrow lasts until the returned RefMut exits scope. The value cannot be borrowed while this borrow is active.

Panics

Panics if the value is currently borrowed.

pub fn try_borrow_mut(&self) -> Result<RefMut<'_, T>, BorrowMutError>

Tries borrowing the wrapped value mutably.

The borrow lasts until the returned RefMut exits scope. The value cannot be borrowed while this borrow is active.

Trait Implementations

impl<T> Clone for RefCell<T>where T: Clone,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Default for RefCell<T>where T: Default,

fn default() -> RefCell<T>

Returns the “default value” for a type.

impl<T> PartialEq<RefCell<T>> for RefCell<T>where T: PartialEq<T> + ?Sized,

fn eq(&self, other: &RefCell<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> Eq for RefCell<T>where T: Eq + ?Sized,

impl<T> Send for RefCell<T>where T: Send + ?Sized,
