Or

Enum Or 

Source
pub enum Or<L, R> {
    Left(L),
    Right(R),
}
Expand description

An enum that represents one of two possible types (Left or Right). When serialized, it writes only the inner value without any discriminant. The discriminant must be managed externally (e.g., via a separate boolean field).

Variants§

§

Left(L)

The left variant.

§

Right(R)

The right variant.

Implementations§
