Returns the embedded result.

Attributes

def map[U](f: Nothing => U): ParseResult[U]

Functional composition of ParseResults.

Functional composition of ParseResults.

Value parameters

f

the function to be lifted over this result

Attributes

Returns

f applied to the result of this ParseResult, packaged up as a new ParseResult

def mapPartial[U](f: PartialFunction[Nothing, U], error: Nothing => String): ParseResult[U]

Partial functional composition of ParseResults.

Partial functional composition of ParseResults.

Value parameters

error

a function that takes the same argument as f and produces an error message to explain why f wasn't applicable (it is called when this is the case)

f

the partial function to be lifted over this result

Attributes

Returns

if f f is defined at the result in this ParseResult, f applied to the result of this ParseResult, packaged up as a new ParseResult. If f is not defined, Failure.
