Trait effect_monad::EffectMonad [−] [src]

pub trait EffectMonad<A>: Sized {
    fn bind<B, Eb, F>(self, f: F) -> BoundEffect<Self, F> where Eb: FnOnce() -> B, F: FnOnce(A) -> Eb;

    fn bind_ignore_contents<B, Eb>(self, eb: Eb) -> BoundEffect<Self, ResolveFn<Eb>> where Eb: FnOnce() -> B { ... }
}

Monad trait for effect functions

Required Methods

fn bind<B, Eb, F>(self, f: F) -> BoundEffect<Self, F> where Eb: FnOnce() -> B, F: FnOnce(A) -> Eb

Sequentially composes two effect functions, passing the output of the first to the input of the second

Provided Methods

fn bind_ignore_contents<B, Eb>(self, eb: Eb) -> BoundEffect<Self, ResolveFn<Eb>> where Eb: FnOnce() -> B

Sequentially composes the two effects, while ignoring the return values of the effects. Similar to the >> function in Haskell, but without returning the value of the second Monad.

Shorthand for rust effectMonad.bind(|_| someOtherEffectMonad);
