Trait borrow_with_ref_obj::BorrowMutWithRefObj

pub trait BorrowMutWithRefObj<'refr, T: 'refr + ?Sized> {
    type ReferenceMut: DerefMut<Target = T> + 'refr;
    fn borrow_mut(&'refr mut self) -> Self::ReferenceMut;
}

Mutable borrower whose reference is an object.

See the crate documentation for more info.

Associated Types

type ReferenceMut: DerefMut<Target = T> + 'refr

Type of the reference object.

Unlike Borrow and BorrowMut, the type may be (and usually is) different than the immutable version of the reference.

Required Methods

fn borrow_mut(&'refr mut self) -> Self::ReferenceMut

Borrows the object mutably.

Panics

May panic if borrowing a borrowed RefCell, a poisoned Mutex or RwLock, or some other implementation-defined issue.
