Codecs

Many tasks in Krop require converting to and from some external representation. For example, dealing with path segments, query parameters, or form submissions all requires converting values to and from strings. Types that handle these conversions are called codecs, which is short for "coder and decoder".

Some codecs, such as Entity, have their own documentation. This section documents StringCodec and SeqStringCodec. They are usually used as given values in constructing Param, Query, and FormCodec values, so the developer typically doesn't work with them directly if a predefined instance already exists for the types they are using.

StringCodec

StringCodec decodes a String to a value and encodes a value as a String.

SeqStringCodec

SeqStringCodec decodes a Seq[String] to a value and encodes a value as a Seq[String].
