# circe AST support

// TODO
# AST support
In some cases, you may need to work with raw AST,
so tethys can offer you circe and json4s AST support:

# json4s AST support
## circe AST support
```scala
import tethys._
import tethys.jackson._
import tethys.derivation.auto._
import tethys.circe._

In some cases, you may need to work with raw AST,
so tethys can offer you json4s AST support:
import io.circe.Json

case class Foo(bar: Int, baz: Json)

val json = """{"bar": 1, "baz": ["some", {"arbitrary": "json"}]}"""
val foo = json.jsonAs[Foo].fold(throw _, identity)

foo.bar // 1: Int
foo.baz // [ "some", { "arbitrary" : "json" } ]: io.circe.Json
```

## json4s AST support
```scala
import tethys._
import tethys.jackson._
