Supports creation of a coproduct codec.
Supports creation of a coproduct codec. See scodec.codecs.CoproductCodecBuilder for details.
When called on a Codec[A] where A is not a subytpe of HList, creates a new codec that encodes/decodes an HList of B :: A :: HNil.
When called on a Codec[A] where A is not a subytpe of HList, creates a new codec that encodes/decodes an HList of B :: A :: HNil.
For example,
uint8 :: utf8
has type Codec[Int :: String :: HNil].
uint8 :: utf8
}}}
When called on a Codec[A], returns a new codec that encodes/decodes B :: A :: HNil.
When called on a Codec[A], returns a new codec that encodes/decodes B :: A :: HNil.
HList equivalent of ~>.
Assuming B is Unit, creates a Codec[A] that: encodes the A followed by a unit;
decodes an A followed by a unit and discards the decoded unit.
Creates a new codec that encodes/decodes an HList type of A :: L given a function A => Codec[L].
Creates a new codec that encodes/decodes an HList type of A :: L given a function A => Codec[L].
This allows later parts of an HList codec to be dependent on earlier values.

Returns a new codec that encodes/decodes a value of type (A, B) where the codec of B is dependent on A.
Transforms using implicitly available evidence that such a transformation is possible.
Transforms using implicitly available evidence that such a transformation is possible.
Typical transformations include converting:
F[L] for some L <: HList to/from an F[CC] for some case class CC, where the types in the case class are
aligned with the types in LF[C] for some C <: Coproduct to/from an F[SC] for some sealed class SC, where the component types in
the coproduct are the leaf subtypes of the sealed class.

Converts this codec to a new codec that compacts the encoded bit vector before returning it.
Converts this codec to a new codec that fails decoding if there are remaining bits.
Similar to flatZip except the A type is not visible in the resulting type -- the binary
effects of the Codec[A] still occur though.

effects of the Codec[A] still occur though.
Example usage:
case class Flags(x: Boolean, y: Boolean, z: Boolean) (bool :: bool :: bool :: ignore(5)).consume { flgs => conditional(flgs.x, uint8) :: conditional(flgs.y, uint8) :: conditional(flgs.z, uint8) } { case x :: y :: z :: HNil => Flags(x.isDefined, y.isDefined, z.isDefined) } }
Note that when B is an HList, this method is equivalent to using flatPrepend and
derive. That is,
a.consume(f)(g) === a.flatPrepend(f).derive[A].from(g).
