Struct Mapped 

pub struct Mapped<Brand>(pub PhantomData<Brand>);

A wrapper struct for the mapped constructor.

Tuple Fields

0: PhantomData<Brand>

Trait Implementations

impl<Brand: Clone> Clone for Mapped<Brand>

fn clone(&self) -> Mapped<Brand>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, I, Brand, A, B> IndexedSetterFunc<'a, I, <Brand as Kind_cdc7cd43dac7585f>::Of<'a, A>, <Brand as Kind_cdc7cd43dac7585f>::Of<'a, B>, A, B> for Mapped<Brand>

where Brand: FunctorWithIndex<I>, A: 'a, B: 'a, I: 'a,

Type Parameters

• 'a: The lifetime of the values.
• I: The index type.
• Brand: The brand of the functor.
• A: The type of the elements in the structure.
• B: The type of the elements in the result.

fn apply( &self, f: Box<dyn Fn(I, A) -> B + 'a>, s: <Brand as Kind_cdc7cd43dac7585f>::Of<'a, A>, ) -> <Brand as Kind_cdc7cd43dac7585f>::Of<'a, B>

Type Signature

forall I Brand A B. FunctorWithIndex Brand => (&Mapped I Brand A B, dyn ((I, A) -> B), Brand A) -> Brand B

Parameters

• &self: The mapped struct.
• f: The map function.
• s: The structure to map.

Returns

The mapped structure.

Examples

use fp_library::{
	brands::{
		VecBrand,
		optics::*,
	},
	types::optics::{
		IndexedSetterFunc,
		Mapped,
	},
};

let mapper = Mapped::<VecBrand>(std::marker::PhantomData);
let s = vec![10, 20, 30];
let f = Box::new(|i: usize, a: i32| a + i as i32);

let result: Vec<i32> = IndexedSetterFunc::apply(&mapper, f, s);

assert_eq!(result, vec![10, 21, 32]);
