Trait table::util::convert::TryAsMut [−][src]
pub trait TryAsMut<T> where
T: ?Sized, { fn try_as_mut(&mut self) -> Option<&mut T>; }
An analogue of AsMut that allows failure, useful when the inner
referenced value isn't present due to an enum mismatch.
Required Methods
fn try_as_mut(&mut self) -> Option<&mut T>
Attempt to unwrap the inner reference.
