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 L
F[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]
.
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
.

Supports TransformSyntax.
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)
.
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
.
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.
