Trait fmap::ContravariantMut

pub trait ContravariantMut<'a, A>where
    Self: ContravariantSelf<'a, A>,
    A: 'a,{
    // Required method
    fn contramap_mut<F>(&mut self, f: F)
       where F: 'a + Send + FnMut(&mut Self::Inner);
}

Same as ContravariantSelf but works on &mut self

Required Methods

fn contramap_mut<F>(&mut self, f: F)where F: 'a + Send + FnMut(&mut Self::Inner),

Same as Contravariant::contramap_fn_mutref but works on &mut self
