I want to create a Decoder which only matches a specific string value, and fails with all others:
onlyMatchesHello :: Json.Decode.Decoder () onlyMatchesHello = -- what goes here? Json.Decode.decodeString onlyMatchesHello "\"hello\"" == Ok () Json.Decode.decodeString onlyMatchesHello "\"something else\"" == Err ... Any idea how to do this? -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group.
