orElse<L1> abstract method

Either<L1, R> orElse<L1>(
  1. Either<L1, R> onLeft(
    1. L l
    )
)

If this Either is Left, return the result of onLeft.

Used to recover from errors, so that when this value is Left you try another function that returns an Either.

Implementation

Either<L1, R> orElse<L1>(Either<L1, R> Function(L l) onLeft);
