Enum icu_provider_adapters::either::EitherProvider

pub enum EitherProvider<P0, P1> {
    A(P0),
    B(P1),
}

A provider that is one of two types determined at runtime.

Data provider traits implemented by both P0 and P1 are implemented on EitherProvider<P0, P1>.

Variants

A(P0)

A value of type P0.

B(P1)

A value of type P1.
