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.Gets this as a Decoder
.
Converts this decoder to a new decoder that fails decoding if there are remaining bits.
Converts this to a codec that fails encoding with an error.
Attempts to decode a value of type A
from the specified bit vector and discards the remaining bits.

Converts this decoder to a Decoder[B]
using the supplied A => Attempt[B]
.
Transforms using two functions, A => Attempt[B]
and B => Attempt[A]
.
Transforms using two functions, A => Attempt[B]
and B => Attempt[A]

Converts this decoder to a Decoder[B]
using the supplied A => Decoder[B]
.
Converts this decoder to a Decoder[B]
using the supplied A => B

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
.
When called on a Decoder[C]
where C
is a coproduct containing type A
, converts to a Decoder[Option[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
