Implementations§

source§

impl<'a, T: ?Sized> Ref<'a, T>

source

pub fn clone(orig: &Ref<'a, T>) -> Ref<'a, T>

Clone the provided Ref value. This is treated as a separate borrow record from the original cloned reference.

source

pub fn map<U: ?Sized, F>(orig: Ref<'a, T>, f: F) -> Ref<'a, U>where F: FnOnce(&T) -> &U,
