Enum sp_runtime::Either
source · [−]pub enum Either<L, R> {
Left(L),
Right(R),
}
Expand description
The enum Either
with variants Left
and Right
is a general purpose
sum type with two cases.
The Either
type is symmetric and treats its variants the same way, without
preference.
(For representing success or error, use the regular Result
enum instead.)
Variants
Left(L)
A value of type L
.
Right(R)
A value of type R
.
