Trait BiFoldMapDispatch 

pub trait BiFoldMapDispatch<'a, FnBrand, Brand: Kind_266801a817966495, A: 'a, B: 'a, M, FA, Marker> {
    // Required method
    fn dispatch(self, fa: FA) -> M;
}

Trait that routes a bi_fold_map operation to the appropriate type class method.

(Fn(A) -> M, Fn(B) -> M) resolves to Val, (Fn(&A) -> M, Fn(&B) -> M) resolves to Ref.

Type Parameters

• 'a: The lifetime of the values.
• FnBrand: The brand of the cloneable function to use.
• Brand: The brand of the bifoldable structure.
• A: The type of the first-position elements.
• B: The type of the second-position elements.
• M: The monoid type.
• FA: The container type (owned or borrowed), inferred from the argument.
• Marker: Dispatch marker type, inferred automatically.

Required Methods

fn dispatch(self, fa: FA) -> M

Perform the dispatched bi_fold_map operation.

Type Signature

(self, FA) -> M

Parameters

• self: The closure tuple implementing this dispatch.
• fa: The structure to fold.

Returns

The combined monoid value.

Examples

use fp_library::{
	brands::*,
	functions::explicit::*,
};
let x: Result<i32, i32> = Ok(5);
let y = bi_fold_map::<RcFnBrand, ResultBrand, _, _, _, _, _>(
	(|e: i32| e.to_string(), |s: i32| s.to_string()),
	x,
);
assert_eq!(y, "5".to_string());

• 'a: The lifetime.
• 'b: The borrow lifetime.
• FnBrand: The cloneable function brand.
• Brand: The bifoldable brand.
• A: The first element type.
• B: The second element type.
• M: The monoid type.
• F: The first closure type.
• G: The second closure type.

fn dispatch(self, fa: &'b <Brand as Kind_266801a817966495>::Of<'a, A, B>) -> M

Type Signature

forall Brand A B M. (RefBifoldable Brand, Monoid M) => ((&A -> M, &B -> M), &Brand A B) -> M

Parameters

• self: The closure tuple.
• fa: A reference to the structure to fold.

Returns

The combined monoid value.

Examples

use fp_library::{
	brands::*,
	functions::explicit::*,
};
let x: Result<i32, i32> = Ok(5);
let y = bi_fold_map::<RcFnBrand, ResultBrand, _, _, _, _, _>(
	(|e: &i32| e.to_string(), |s: &i32| s.to_string()),
	&x,
);

fn dispatch(self, fa: <Brand as Kind_266801a817966495>::Of<'a, A, B>) -> M

Type Signature

forall Brand A B M. (Bifoldable Brand, Monoid M) => ((A -> M, B -> M), Brand A B) -> M

Parameters

• self: The closure tuple.
