Expand description
Applying wrapped by-ref functions within contexts with ref_apply.
Like Semiapplicative::apply, but the
wrapped functions receive &A instead of owned values. Uses
CloneFn<Ref> for the function wrappers.
§Examples
use fp_library::{
brands::*,
classes::*,
functions::*,
types::*,
};
let f = RcLazy::pure(std::rc::Rc::new(|x: &i32| *x * 2) as std::rc::Rc<dyn Fn(&i32) -> i32>);
let x = RcLazy::pure(5);
let result = ref_apply::<RcFnBrand, LazyBrand<RcLazyConfig>, _, _>(&f, &x);
assert_eq!(*result.evaluate(), 10);Traits§
- RefSemiapplicative
- A type class for applying wrapped by-ref functions within contexts.
