upickle.implicits

Basic functionality to be able to read and write objects. Kept as a trait so other internal files can use it, while also mixing it into the upickle package to form the public API1

Auto-generated picklers and unpicklers, used for creating the 22 versions of tuple-picklers and case-class picklers

This needs to be split into a separate trait due to https://github.com/scala/bug/issues/11768

Annotation for fine-grained control of the def allowUnknownKeys configuration on the upickle bundle; can be applied to individual case classes, taking precedence over upickle pickler-level configuration

An annotation that, when applied to a field in a case class, flattens the fields of the annotated case class or Iterable into the parent case class during serialization. This means the fields will appear at the same level as the parent case class's fields rather than nested under the field name. During deserialization, these fields are grouped back into the annotated case class or Iterable.

Limitations:

• Only works with collections type that are subtypes of Iterable[(String, _)].
• Cannot flatten more than two collections in a same level.

Annotation for control over the strings used to serialize your data structure. Can be applied in three ways:

1. To individual fields, in which case it overrides the JSON object fieldname

2. To case classes which are part of sealed traits, where it overrides the value of the "$type": "foo" discriminator field

3. To sealed traits themselves, where it overrides the key of the "$type": "foo" discriminator field
