Struct accountable_refcell::RefCell

pub struct RefCell<T: ?Sized> {
    pub(crate) borrows: RefCell<BorrowData>,
    pub(crate) inner: RefCell<T>,
}

A RefCell that tracks outstanding borrows and reports stack traces for dynamic borrow failures.

Fields

borrows: RefCell<BorrowData>

inner: RefCell<T>

Implementations

impl<T> RefCell<T>

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

Create a new RefCell value.

pub fn into_inner(self) -> T

Discard this RefCell and return the value stored inside of it.

impl<T: ?Sized> RefCell<T>

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

Borrow the value stored in this cell immutably. Panics if any outstanding mutable borrows of the same cell exist.

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

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

Borrow the value stored in this cell mutably. Panics if there are any other outstanding borrows of this cell (mutable borrows are unique, i.e. there can only be one).

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

pub fn as_ptr(&self) -> *mut T

pub unsafe fn try_borrow_unguarded(&self) -> Result<&T, BorrowError>

impl<T> RefCell<T>

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

Corresponds to https://doc.rust-lang.org/std/cell/struct.RefCell.html#method.replace.

pub fn replace_with<F: FnOnce(&mut T) -> T>(&self, f: F) -> T

Corresponds to https://doc.rust-lang.org/std/cell/struct.RefCell.html#method.replace_with.

impl<T: Default> RefCell<T>

pub fn take(&self) -> T

Corresponds to https://doc.rust-lang.org/std/cell/struct.RefCell.html#method.take.

Trait Implementations

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

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: Debug + ?Sized> Debug for RefCell<T>

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

Formats the value using the given formatter.

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

fn default() -> RefCell<T>

Returns the “default value” for a type.

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

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.
