OptionalValidatingQueryParamDecoderMatcher

abstract class OptionalValidatingQueryParamDecoderMatcher[T] extends AnyRef

param extractor using org.http4s.QueryParamDecoder. Note that this will _always_ match, but will return an Option possibly containing the result of the conversion to T

case class Foo(i: Int)
implicit val fooDecoder: QueryParamDecoder[Foo] = ...

case class Bar(i: Int)
implicit val barDecoder: QueryParamDecoder[Bar] = ...

object FooMatcher extends ValidatingQueryParamDecoderMatcher[Foo]("foo")
object BarMatcher extends OptionalValidatingQueryParamDecoderMatcher[Bar]("bar")

val service: HttpService = {
case GET -> Root / "closest" :? FooMatcher(fooValue) +& BarMatcher(barValue) => {
  ^(fooValue, barValue getOrElse 42.right) { (foo, bar) =>
    ...
  }.fold(
    nelE => BadRequest(nelE.toList.map(_.sanitized).mkString("\n")),
    baz  => { ... }
  )
