Trait collectable::TryExtend

pub trait TryExtend<A> {
    type Error;
    fn try_extend<T>(&mut self, iter: &mut T) -> Result<(), Self::Error>
    where
        T: Iterator<Item = A>;

    fn try_extend_from_slice(&mut self, slice: &[A]) -> Result<(), Self::Error>
    where
        A: Clone,
    { ... }
}
