matchWithStringOtherwise

matchWithStringOtherwise() handles selected values of a Clean string primitive. Raw string values form the matcher keys. Missing cases are sent to otherwise, which receives the original primitive narrowed to the remaining values.

Syntax

Classic signature

function matchWithStringOtherwise<Input extends Primitive<string>, Matcher, Output>(
  input: Input,
  matcher: Matcher,
  otherwise: (value: UnhandledPrimitive) => Output
): MatcherResult | Output

Curried signature

function matchWithStringOtherwise<Input extends Primitive<string>, Matcher, Output>(
  matcher: Matcher,
  otherwise: (value: UnhandledPrimitive) => Output
): (input: Input) => MatcherResult | Output

Parameters

• input: a Clean string primitive with literal values.
• matcher: a partial object indexed by raw values from the primitive. Unknown keys are rejected.
• otherwise: receives the original Primitive, ConstrainedType, or NewType, narrowed to values without a handler.

Return value

The selected handler result, or the otherwise result for an unhandled wrapped value.
