Result
This trait represents the result of a parser.
Either a Success[A]
or a Failure
.
Attributes
- A
the type of expected success result.
- Source:
- Result.scala
- Graph
- Supertypes
- Known subtypes
Members list
Value members
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.
- Since:
1.7.0
- Note:
the result must not be a failure.
- Source:
- Result.scala
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.
Attributes
- elem
the element to test.
- Returns:
true
if this is aSuccess
value equal toelem
.- Since:
1.7.0
- Source:
- Result.scala
Returns false
if Failure
or returns the result of the application of
the given predicate to the Success
value.
Returns false
if Failure
or returns the result of the application of
the given predicate to the Success
value.
Attributes
- Since:
1.7.0
- Source:
- Result.scala
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
.
Attributes

- Source:
- Result.scala
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.
Attributes
- Since:
1.7.0
- Source:
- Result.scala
Returns the nested result if this result is a success, otherwise return this failure.
Returns the nested result if this result is a success, otherwise return this failure.
Equivalent to flatMap(identity[Result[Errʹ, B]])
.

Returns the result of applying ferr
to this result's error if this is a Failure
or fa
to the result stored in the Success
otherwise.
Returns the result of applying ferr
to this result's error if this is a Failure
or fa
to the result stored in the Success
otherwise.
Attributes
- fa
the function to apply if this is a
Success
.- ferr
the function to apply if this is a
Failure
.- Returns:
the results of applying the function

Returns true
if this result is a Failure
or returns the result of the application of
the given predicate to the Success
value.
Returns true
if this result is a Failure
or returns the result of the application of
the given predicate to the Success
value.

Executes the procedure f
if this is a Success
.
Executes the procedure f
if this is a Success
. Otherwise, do nothing.
This is equivalent to:
result match {
case Success(x) => f(x)
case _ => ()
}
Attributes
- f
The side-effecting function to execute.
- Since:
1.7.0
- Source:
- Result.scala
Returns the value from this Success
or the result of evaluating default
if this is a Failure
.
Returns the value from this Success
or the result of evaluating default
if this is a Failure
.
Attributes

- Result.scala
Returns a Success
containing the result of applying f
to this result's value if
this is a success.
Returns a Success
containing the result of applying f
to this result's value if
this is a success. Otherwise, returns a failure.
