final class CoproductCodecBuilder[C <: Coproduct, L <: HList, R] extends AnyRef
Supports building a coproduct codec.
A coproduct codec is built by:
- specifying a codec for each member of the coproduct, separated by the
:+:
operator - specifying the discriminator codec and mapping between discriminator values and coproduct members
- alternatively, instead of specifying a discriminator codec, using the
choice
combinator to create a codec that encodes no discriminator and hence, decodes by trying each codec in succession and using the first successful result
To specify the discriminator, call either discriminatedByIndex(intCodec)
or discriminatedBy(codec)
followed by
one of the methods on NeedDiscriminators. The former uses the type index as the discriminator value.
For example:
(int32 :+: bool(8) :+: variableSizeBytes(uint8, ascii)).discriminatedByIndex(uint8)
The first 8 bits of the resulting binary contains the discriminator value due to usage of the uint8
codec as
the discriminator codec. A discriminator value of 0 causes the remaining bits to be encoded/decoded with int32
.
Similarly, a value of 1 causes the remaining bits to be encoded/decoded with bool(8)
and a value of 2 causes
the remaining bits to be encoded/decoded as a sized ASCII string.
Alternatively, discriminator values can be explicitly specified using discriminatedBy(codec).using(Sized(...))
.
For example:
(int32 :+: bool(8) :+: variableSizeBytes(uint8, ascii)).discriminatedBy(fixedSizeBytes(1, ascii)).using(Sized("i", "b", "s"))
In this example, integers are associated with the discriminator i
, booleans with b
, and strings with s
. The discriminator
is encoded with fixedSizeBytes(1, ascii)
.
The methods which generate a Codec
return a Codec[R]
instead of a Codec[C]
. Typically, C =:= R
but the xmap
and
exmap
methods allow transformations between C
and R
to be deferred until after the codec is built.
