Trait interior_mut::InteriorMut

pub trait InteriorMut<'a, T> {
    type RefMut: DerefMut<Target = T> + 'a;
    type Error;
    fn borrow_int_mut(&'a self) -> Result<Self::RefMut, Self::Error>;
}

A trait for obtaining a mutable reference on types that allow interior mutability.

Associated Types

type RefMut: DerefMut<Target = T> + 'a

The reference type

type Error

The error type

Required Methods

fn borrow_int_mut(&'a self) -> Result<Self::RefMut, Self::Error>

Mutably borrows the internal value from an immutable reference.
