Abstract methods

def flatMap[EE >: E <: Throwable, B](f: A => ErrBi[EE, B]): ErrBi[EE, B]

Classic flatMap function as we see on a Scala Option.

Attributes

def flatMapAcc[EE >: E <: Throwable, B](f: A => ErrBiAcc[EE, B])(using ctE: ClassTag[EE], ctB: ClassTag[B]): ErrBiAcc[EE, B]

If this ErrBi is a Succ produce and ErrBi accumulator with the parameter function.

If this ErrBi is a Succ produce and ErrBi accumulator with the parameter function.

Attributes

def fld[B](fFail: E => B, fSucc: A => B): B

Alternative fold, that only takes one parameter list. this ErrBi into a type B. Takes two function parameters, one converts from A to B as in a normal map method. The second parameter in its own parameter list converts from the Error type to type B.

Attributes

def fold[B](fFail: E => B)(fSucc: A => B): B

Fold this ErrBi into a type B. Takes two function parameters, one converts from A to B as in a normal map method. The second parameter in its own parameter list converts from the Error type to type B.

Attributes

def forFld(fErr: E => Unit, fSucc: A => Unit): Unit

This is just a Unit returning fold, but is preferred because the method is explicit that it is called for effects, rather than to return a value. This method is implemented in the leaf Succ and Fail classes to avoid boxing.

Attributes

def forSucc(f: A => Unit): Unit

Will perform action if success. Does nothing if Fail.

Will perform action if success. Does nothing if Fail.

Attributes

def isFail: Boolean

True if this is a fail error.

True if this is a fail error.

Attributes

def isSucc: Boolean

True if this is a successful Succ value.

True if this is a successful Succ value.

Attributes

def map[B](f: A => B): ErrBi[E, B]

Classic map function as we see on a Scala Option or List.

Classic map function as we see on a Scala Option or List.

Attributes

def succOrOther[EE >: E <: Throwable, AA >: A](otherErrBi: => ErrBi[EE, AA]): ErrBi[EE, AA]

Returns this if success, else returns the other ErrBi.

Returns this if success, else returns the other ErrBi.

Attributes

Attributes

def findTypeForeach[A : Unshow](f: A => Unit): Unit
Extension method from ErrBi

Extension method to map this ErrBi String to find a value of the given type from the String parsed as RSON and then perform a foreach on the value if successful.

Attributes

def flatOptMap[B](f: A => Option[B]): ErrBi[E | ExcNFT, B]

Classic flatMap function taking a function from A => Option[B] rather than the standard ErrBi of B.

Classic flatMap function taking a function from A => Option[B] rather than the standard ErrBi of B.

Attributes

def get: A
final def getElse(elseValue: A): A

Gets the value of Good or returns the elseValue parameter if Bad. Both Good and Bad should be implemented in the leaf classes to avoid unnecessary boxing of primitive values.
