Struct ProfunctorFirstAppliedBrand 

pub struct ProfunctorFirstAppliedBrand<Brand, A>(/* private fields */);

An adapter that partially applies a Profunctor to its first argument, creating a Functor.

Examples

use fp_library::{
	brands::*,
	classes::functor::map,
};

let f = |x: i32| x + 1;
let g = map::<ProfunctorFirstAppliedBrand<RcFnBrand, i32>, _, _>(
	|y: i32| y * 2,
	std::rc::Rc::new(f) as std::rc::Rc<dyn Fn(i32) -> i32>,
);
assert_eq!(g(10), 22); // (10 + 1) * 2 = 22

forall Brand A B C. Profunctor Brand => (B -> C, ProfunctorFirstApplied Brand A B) -> ProfunctorFirstApplied Brand A C

Type Parameters

• 'a: The lifetime of the values.
• B: The input type.
• C: The output type.

Parameters

• f: The function to apply.
• fa: The profunctor value to map over.

Returns

The mapped profunctor value.

Examples

use fp_library::{
	brands::*,
	functions::*,
};

let f = std::rc::Rc::new(|x: i32| x + 1) as std::rc::Rc<dyn Fn(i32) -> i32>;
let g = map::<ProfunctorFirstAppliedBrand<RcFnBrand, i32>, _, _>(|x: i32| x * 2, f);
assert_eq!(g(5), 12); // (5 + 1) * 2

impl<Brand: Hash, A: Hash> Hash for ProfunctorFirstAppliedBrand<Brand, A>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

type Of<'a, B: 'a> = <Brand as Kind_266801a817966495>::Of<'a, A, B>

The applied type.

impl<Brand: Ord, A: Ord> Ord for ProfunctorFirstAppliedBrand<Brand, A>

fn cmp(&self, other: &ProfunctorFirstAppliedBrand<Brand, A>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<Brand: PartialEq, A: PartialEq> PartialEq for ProfunctorFirstAppliedBrand<Brand, A>

fn eq(&self, other: &ProfunctorFirstAppliedBrand<Brand, A>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<Brand: PartialOrd, A: PartialOrd> PartialOrd for ProfunctorFirstAppliedBrand<Brand, A>

fn partial_cmp( &self, other: &ProfunctorFirstAppliedBrand<Brand, A>, ) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
