Network.HTTP.Types.QueryLike

Synopsis

Documentation

class QueryLike a where #

Types which can, and commonly are, converted to Query are in this class.

You can use lists of simple key value pairs, with ByteString (strict, or lazy: ByteString), Text, or String as the key/value types. You can also have the value type lifted into a Maybe to support keys without values; and finally it is possible to put each pair into a Maybe for key-value pairs that aren't always present.
