Module carboxyl::lift
+
+ [−]
+
+ [src]
+Lifting of n-ary functions.
+ +A lift maps a function on values to a function on signals. Given a function of
+type F: Fn(A, B, …) -> R and signals of types Signal<A>, Signal<B>, … the
+lift! macro creates a Signal<R>, whose content is computed using the
+function.
Currently lift is only implemented for functions with up to four arguments. +This limitation is due to the current implementation strategy (and maybe +limitations of Rust's type system), but it can be increased to arbitrary but +finite arity if required.
+ +Example
+let sink_a = Sink::new(); +let sink_b = Sink::new(); +let product = lift!( + |a, b| a * b, + &sink_a.stream().hold(0), + &sink_b.stream().hold(0) +); +assert_eq!(product.sample(), 0); +sink_a.send(3); +sink_b.send(5); +assert_eq!(product.sample(), 15); ++
