final class JsoniterScalaCodec(maxDepth: Int, initialSize: Int, doSerialize: Json => Boolean, numberParser: JsonReader => Json, numberSerializer: (JsonWriter, JsonNumber) => Unit) extends JsonValueCodec[Json]

A JSON value codec that parses and serialize to/from circe's JSON AST.

Value parameters

initialSize

the initial size hint for object and array collections

maxDepth

the maximum depth for decoding

numberParser

a function that parses JSON numbers

numberSerializer

a function that serializes JSON numbers

Concrete methods

override def decodeValue(in: JsonReader, default: Json): Json

Attempts to decode a value of type A from the specified JsonReader, but may fail with JsonReaderException error if the JSON input does not encode a value of this type.

Value parameters

default

the placeholder value provided to initialize some possible local variables

in

override def encodeValue(x: Json, out: JsonWriter): Unit

Encodes the specified value using provided JsonWriter, but may fail with JsonWriterException if it cannot be encoded properly according to RFC-8259 requirements.

Concrete fields

override val nullValue: Json

Returns some placeholder value that will be used by the high level code that generates codec instances to initialize local variables for parsed field values which have a codec that was injected using implicit val.
