circe-derivation | Fast type class instance derivation for Circe

circe-derivation is a Scala library. circe-derivation has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This library provides macro-supported derivation of circe's type class instances. It differs from circe-generic in that this derivation is not based on Shapeless's generic representation of case classes and ADTs, and it is not intended to be as fully featured as io.circe.generic. Notably fully automatic derivation is a non-goal. The only targeted remaining feature for parity is constructor renaming. In return for losing automatic derivation you get a library that has no dependencies apart from circe-core, should compile much more quickly in most cases, and supports some classes that circe-generic doesn't (e.g. Scrooge-generated representations of Thrift structs).
