Runs the sequenced decoding operations by decoding the specified bit vector.
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.
Transforms using two functions, A => Attempt[B] and B => Attempt[A].
Transforms using two functions, A => Attempt[B] and B => Attempt[A].
Curried version of exmap.
Curried version of exmap.
Returns a context that first decodes using this context, then uses the decoded value and the supplied function to generate a subsequent context, and decodes the remainder of the first decoding operation with the subsequent context.
Transforms the decoded value using the supplied function.
Transforms the decoding error using the supplied function.
Transforms using two functions, A => Attempt[B] and B => A.
Transforms using two functions, A => Attempt[B] and B => A.
The supplied functions form an injection from B to A. Hence, this method converts from
a larger to a smaller type. Hence, the name narrow.
Curried version of narrow.
Curried version of narrow.

Converts this context to a decoder instance.
Transforms using two functions, A => B and B => Attempt[A].
Transforms using two functions, A => B and B => Attempt[A].
The supplied functions form an injection from A to B. Hence, this method converts from
a smaller to a larger type. Hence, the name widen.
Transforms using two functions, A => B and B => Option[A].
Transforms using two functions, A => B and B => Option[A].
Particularly useful when combined with case class apply/unapply. E.g., widenOpt(fa, Foo.apply, Foo.unapply).
Curried version of widenOpt.
Curried version of widenOpt.
Curried version of widen.
Curried version of widen.
Transforms using the isomorphism described by two functions, A => B and B => A.
Transforms using the isomorphism described by two functions, A => B and B => A.
Curried version of xmap.
Curried version of xmap.
Transforms using two functions, A => B and B => Option[A].
Transforms using two functions, A => B and B => Option[A].
Particularly useful when combined with case class apply/unapply. E.g., pxmap(fa, Foo.apply, Foo.unapply).
(Since version 1.7.0) Use widenOpt instead
Provides the ability to sequence decoding operations such that the remainder of an operation is fed in to the input of the next operation. This is useful when using codecs in for comprehensions for decoding purposes.
Note: this is a domain specific fail fast state monad.
(Since version 1.8.2) Use flatMap on Codec or Decoder, which provides equivalent functionality
