Trait FilterDispatch 

pub trait FilterDispatch<'a, Brand: Kind_cdc7cd43dac7585f, A: 'a + Clone, FA, Marker> {
    // Required method
    fn dispatch(self, fa: FA) -> <Brand as Kind_cdc7cd43dac7585f>::Of<'a, A>;
}

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

The Marker type parameter is an implementation detail resolved by the compiler from the closure’s argument type; callers never specify it directly. The FA type parameter is inferred from the container argument: owned for Val dispatch, borrowed for Ref dispatch.

Type Parameters

• 'a: The lifetime of the values.
• Brand: The brand of the filterable.
• A: The type of the value(s) inside the filterable.
• FA: The container type (owned or borrowed), inferred from the argument.
• Marker: Dispatch marker type, inferred automatically. Either Val or Ref.

Required Methods

fn dispatch(self, fa: FA) -> <Brand as Kind_cdc7cd43dac7585f>::Of<'a, A>

Perform the dispatched filter operation.

Type Signature

(self, FA) -> Brand A

Parameters

• self: The closure implementing this dispatch.
• fa: The filterable instance containing the value(s).

Returns

A new filterable instance containing only the values for which the predicate returned true.

Examples

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

let result = filter::<OptionBrand, _, _, _>(|x: i32| x > 3, Some(5));
assert_eq!(result, Some(5));

Implementors

impl<'a, 'b, Brand, A, F> FilterDispatch<'a, Brand, A, &'b <Brand as Kind_cdc7cd43dac7585f>::Of<'a, A>, Ref> for F

where Brand: RefFilterable, A: 'a + Clone, F: Fn(&A) -> bool + 'a,

Routes Fn(&A) -> bool closures to RefFilterable::ref_filter.

The container must be passed by reference (&fa).

Type Parameters

• 'a: The lifetime of the values.
• 'b: The borrow lifetime.
• Brand: The brand of the filterable.
• A: The type of the value(s) inside the filterable.
• F: The closure type.

impl<'a, Brand, A, F> FilterDispatch<'a, Brand, A, <Brand as Kind_cdc7cd43dac7585f>::Of<'a, A>, Val> for F

where Brand: Filterable, A: 'a + Clone, F: Fn(A) -> bool + 'a,

Routes Fn(A) -> bool closures to Filterable::filter.

Type Parameters

• 'a: The lifetime of the values.
• Brand: The brand of the filterable.
• A: The type of the value(s) inside the filterable.
• F: The closure type.
