Function sequence 

pub fn sequence<'a, ClonableFnBrand: 'a + ClonableFn, Brand: Traversable, F: Applicative, A: 'a + Clone>(
    t: Apply0L1T<Brand, Apply0L1T<F, A>>,
) -> Apply0L1T<F, Apply0L1T<Brand, A>>
where
    Apply0L1T<F, A>: 'a + Clone,
    Apply0L1T<F, ApplyFn<'a, ClonableFnBrand, Apply0L1T<Brand, A>, Apply0L1T<Brand, A>>>: Clone,
    Apply0L1T<Brand, A>: 'a,
    Apply0L1T<Brand, Apply0L1T<F, A>>: 'a,
    Apply0L1T<F, Apply0L1T<Brand, A>>: 'a,

Evaluate each computation in a Traversable structure and accumulate the results into an Applicative context.

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

The default implementation of sequence is implemented in terms of traverse and identity where:

sequence = traverse identity

Type Signature

forall a. Traversable t, Applicative f => t (f a) -> f (t a)

Parameters

• t: A Traversable structure containing Applicative computations.

Returns

An Applicative containing the accumulated results of the computations.

Examples

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

assert_eq!(
    sequence::<RcFnBrand, VecBrand, OptionBrand, i32>(vec![Some(1), Some(2), Some(3)]),
    Some(vec![1, 2, 3])
);
