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.Determines discriminators values automatically by looking for a Discriminator[R, X, A]
for each component type X
in the coproduct C

Curried version of exmap

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

Specifies the discriminator values for each of the union type members by providing the discriminators as a record with the same keys as the union.
Specifies the discriminator values for each of the coproduct type members.
Specifies the discriminator values for each of the coproduct type members.
The collection must list the discriminators in the order that the corresponding types appear in the coproduct.

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
.

Particularly useful when combined with case class apply/unapply. E.g., widenOpt(fa, Foo.apply, Foo.unapply)

Assists in creating a coproduct codec, after the coproduct type and discriminator type have been fixed.
