Function apply 

pub fn apply<'a, ClonableFnBrand: 'a + ClonableFn, Brand: Semiapplicative, A: 'a + Clone, B: 'a>(
    ff: Apply0L1T<Brand, ApplyFn<'a, ClonableFnBrand, A, B>>,
) -> ApplyFn<'a, ClonableFnBrand, Apply0L1T<Brand, A>, Apply0L1T<Brand, B>>

Applies a function within a context to a value within a context.

Free function version that dispatches to the type class’ associated function.

Type Signature

forall a b. Semiapplicative f => f (a -> b) -> f a -> f b

Parameters

• ff: A function wrapped in the context.
• fa: A value wrapped in the context.

Returns

The result of applying the function to the value, all within the context.

Examples

use fp_library::{brands::{OptionBrand, RcFnBrand}, functions::apply};
use std::rc::Rc;

assert_eq!(
    apply::<RcFnBrand, OptionBrand, _, _>(Some(Rc::new(|x: i32| x * 2)))(Some(5)),
    Some(10)
);
