Struct icu_provider_adapters::fork::by_error::ForkByErrorProvider
source · pub struct ForkByErrorProvider<P0, P1, F>(P0, P1, F);
Expand description
A provider that returns data from one of two child providers based on a predicate function.
This is an abstract forking provider that must be provided with a type implementing the
ForkByErrorPredicate
trait.
ForkByErrorProvider
does not support forking between DataProvider
s. However, it
supports forking between AnyProvider
, BufferProvider
, and DynamicDataProvider
.

impl<P0, P1, F> ForkByErrorProvider<P0, P1, F>
sourcepub fn new_with_predicate(p0: P0, p1: P1, predicate: F) -> Self
pub fn new_with_predicate(p0: P0, p1: P1, predicate: F) -> Self
Create a new provider that forks between the two children.
The predicate
argument should be an instance of a struct implementing
ForkByErrorPredicate
.
sourcepub fn inner_mut(&mut self) -> (&mut P0, &mut P1)
pub fn inner_mut(&mut self) -> (&mut P0, &mut P1)
Returns mutable references to the inner providers.
sourcepub fn into_inner(self) -> (P0, P1)
pub fn into_inner(self) -> (P0, P1)
Returns ownership of the inner providers to the caller.

sourcepub fn new(p0: P0, p1: P1) -> Self
pub fn new(p0: P0, p1: P1) -> Self
A provider that returns data from one of two child providers based on the key.
