Result
This trait represents the result of a parser.
Either a Success[A] or a Failure.
Type parameters
- A
-
the type of expected success result.

Abstract methods
Returns the successful value within the result.
Returns the successful value within the result.
This is equivalent to:
result match {
case Success(x) => x
case _ => throw new Exception
}
Attributes
- Throws
-
java.util.NoSuchElementException if the result is a failure.

- Note
-
the result must not be a failure.

Returns true if this is a Failure, false otherwise.
Returns true if this is a Success, false otherwise.
Concrete methods
Returns true if this result is a Success and its value is equal to elem (as determined by ==), returns false otherwise.
Returns true if this result is a Success and its value is equal to elem (as determined by ==), returns false otherwise.

Returns Success with the existing value of Success if this is a Success and the given predicate p holds for the right value, or Failure(msg) if this is a Success and the given predicate p does not hold for the right value, or Failure with the existing value of Failure if this is a Failure.
Returns Success with the existing value of Success if this is a Success and the given predicate p holds for the right value, or Failure(msg) if this is a Success and the given predicate p does not hold for the right value, or Failure with the existing value of Failure if this is a Failure.

Returns the result of applying f to this result if it is a success.
Returns the result of applying f to this result if it is a success. Returns a failure if this result is a failure. Differs from map as f returns a result instead of just a value.
