pub trait PartitionMapDispatch<'a, Brand: Kind_cdc7cd43dac7585f, A: 'a, E: 'a, O: 'a, FA, Marker> {
// Required method
fn dispatch(
self,
fa: FA,
) -> (<Brand as Kind_cdc7cd43dac7585f>::Of<'a, E>, <Brand as Kind_cdc7cd43dac7585f>::Of<'a, O>);
}Expand description
Trait that routes a partition_map 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.E: The error type produced by the partitioning function.O: The success type produced by the partitioning function.FA: The container type (owned or borrowed), inferred from the argument.Marker: Dispatch marker type, inferred automatically. EitherValorRef.
Required Methods§
Sourcefn dispatch(
self,
fa: FA,
) -> (<Brand as Kind_cdc7cd43dac7585f>::Of<'a, E>, <Brand as Kind_cdc7cd43dac7585f>::Of<'a, O>)
fn dispatch( self, fa: FA, ) -> (<Brand as Kind_cdc7cd43dac7585f>::Of<'a, E>, <Brand as Kind_cdc7cd43dac7585f>::Of<'a, O>)
Perform the dispatched partition_map operation.
§Type Signature
(self, FA) -> (Brand E, Brand O)
§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 the Err values, the second contains the Ok values.
§Examples
use fp_library::{
brands::*,
functions::explicit::*,
};
let (errs, oks) =
partition_map::<OptionBrand, _, _, _, _, _>(|x: i32| Ok::<i32, i32>(x * 2), Some(5));
assert_eq!(errs, None);
assert_eq!(oks, Some(10));Implementors§
impl<'a, 'b, Brand, A, E, O, F> PartitionMapDispatch<'a, Brand, A, E, O, &'b <Brand as Kind_cdc7cd43dac7585f>::Of<'a, A>, Ref> for F
Routes Fn(&A) -> Result<O, E> closures to RefFilterable::ref_partition_map.
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.E: The error type produced by the partitioning function.O: The success type produced by the partitioning function.F: The closure type.
impl<'a, Brand, A, E, O, F> PartitionMapDispatch<'a, Brand, A, E, O, <Brand as Kind_cdc7cd43dac7585f>::Of<'a, A>, Val> for F
Routes Fn(A) -> Result<O, E> closures to Filterable::partition_map.
§Type Parameters
'a: The lifetime of the values.Brand: The brand of the filterable.A: The type of the value(s) inside the filterable.E: The error type produced by the partitioning function.O: The success type produced by the partitioning function.F: The closure type.
