[][src]Struct cell::RefValMut

pub struct RefValMut<'b, T> { /* fields omitted */ }

A type containing a value that contains a borrowed mutable reference to a value from a RefCell<T>.

See the module-level documentation for more.

Methods

impl<'b, T> RefValMut<'b, T>[src]

pub fn map<U: Sized, F>(orig: RefValMut<'b, T>, f: F) -> RefValMut<'b, U> where
    F: FnOnce(T) -> U, 
[src]

Make a new RefValMut from the another RefValMut.

The RefCell is already mutably borrowed, so this operation cannot fail.
