Trait borrow_with_ref_obj::BorrowWithRefObj

pub trait BorrowWithRefObj<'refr, T: 'refr + ?Sized> {
    type Reference: Deref<Target = T> + 'refr;
    fn borrow(&'refr self) -> Self::Reference;
}

Immutable borrower whose reference is an object.

See the crate documentation for more info.

Associated Types

type Reference: Deref<Target = T> + 'refr

Type of the reference object.

Required Methods

fn borrow(&'refr self) -> Self::Reference

Borrows the object immutably.

Panics

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