Struct StateRefCell

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

A mutable memory location with dynamically checked borrow rules

This is similar to RefCell but instead of returned wrapped reference, it returns the value directly.

This means that once the value is borrowed to read it will never get available again.

Implementations

impl<T> StateRefCell<T>

pub const fn new(val: T) -> Self

pub fn replace(&self, val: T) -> Option<T>

Panics

Panics if the value is currently borrowed.

pub fn get(&self) -> &T

Panics

Panics if the value is currently mutably borrowed.

pub fn try_get(&self) -> Option<&T>

Tries to get the value if it is not currently borrowed.

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

Panics

Panics if the value is currently borrowed.

pub fn take(&mut self) -> T

Panics

Panics if the value is currently borrowed.
