Expand description

A mutably borrowed reference to a value borrowed from a KCell

Implementations§

source§

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

source

pub fn filter_map<U, F>(borrowed: Self, f: F) -> Result<BorrowMut<'a, U>, Self>
where F: FnOnce(&mut T) -> Option<&mut U>, U: ?Sized,

Makes a new BorrowMut for an optional component of the borrowed data. If the closure returns None then the original borrow is returned as the error.
