PartitionDispatch

Trait PartitionDispatch 

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

Trait that routes a partition 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§

Source

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

Perform the dispatched partition operation.

§Type Signature

(self, FA) -> (Brand A, Brand A)

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

A tuple of two filterable instances: the first contains elements satisfying the predicate, the second contains the rest.

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

let (no, yes) = partition::<OptionBrand, _, _, _>(|x: i32| x > 3, Some(5));
assert_eq!(yes, Some(5));
assert_eq!(no, None);

Implementors§

Source§

impl<'a, 'b, Brand, A, F> PartitionDispatch<'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_partition.

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.
Source§

impl<'a, Brand, A, F> PartitionDispatch<'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::partition.

§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.
