[−][src]Trait casper_node::effect::EffectResultExt

pub trait EffectResultExt {
    type Value;
    type Error;
    fn result<U, F, G>(self, f_ok: F, f_err: G) -> Effects<U>
    where
        F: FnOnce(Self::Value) -> U + 'static + Send,
        G: FnOnce(Self::Error) -> U + 'static + Send,
        U: 'static;
}

Required methods

fn result<U, F, G>(self, f_ok: F, f_err: G) -> Effects<U> where
    F: FnOnce(Self::Value) -> U + 'static + Send,
    G: FnOnce(Self::Error) -> U + 'static + Send,
    U: 'static, 

Finalizes a future returning a Result into two different effects.

The function f_ok is used to translate the returned value from an effect into an event, while the function f_err does the same for a potential error.
