final class DiscriminatorCodec[A, B] extends Codec[A] with KnownDiscriminatorType[B]

Codec that supports the binary structure tag ++ value where the tag identifies the encoding/decoding of the value.

To build an instance of this codec, call discriminated and specify the tag type via the by method. Then call one more more of the case combinators on this class.

Each of the case combinators provides two forms, one that defines a case with a single tag value and another, overloaded form that defines a case with a tag value to use in encoding and a predicate on tag value to use in decoding.

The most general case combinators are caseO and caseP (and their operator equivalents, ? and |). In addition to a tag or tag/predicate pair, the caseO combinators are defined by providing a mapping from A to Option[R], a mapping from R to A, and a Codec[R]. The case is used for encoding if the mapping from A to Option[R] returns a Some and it is used for decoding upon matching the tag value. The caseP combinators work the same but take a PartialFunction[A, R] instead of an A => Option[R].

If R is a subtype of A, then the mapping from R to A can be omitted. Hence, the subcaseO and subcaseP (and the operator equivalents, / and \) constrain R to being a subtype of A and do not take a R => A function.

Finally, the least generic case combinators are the typecase combinators which add further constraints to the subcase* combinators. Specifically, the typecase operators omit the A => Option[R] or PartialFunction[A, R] in favor of doing subtype checks. For example, the following codec is a Codec[AnyVal] that encodes a 0 if passed a Boolean and a 1 if passed an Int:

discriminated[AnyVal].by(uint8).typecase(0, bool).typecase(1, int32)

Often, the values are size-delimited -- that is, there is a size field after the tag field and before the value field. To support this, use the framing method to provide a transformation to each value codec. For example, framing(new CodecTransformation { def apply[X](c: Codec[X]) = variableSizeBytes(uint8, c) }).

    This codec, the Codec[L], is used for encoding/decoding. When decoding, the first value of type A is removed from the HList.

    When encoding, the returned codec computes an A value using the supplied function and inserts the computed A in to the HList M, yielding an HList L. That HList L is then encoded using the original codec.

    This method is called derive because the value of type A is derived from the other fields in the HList L.
