A derivation library for scala 3 with annotation based configuration.

## Usage

This library os being published to the macen central. Add library to your project as

```sbt

addSbtPlugin("com.evolution" % "sbt-artifactory-plugin" % "0.0.2")

libraryDependencies += "com.evolution" %% "derivation-circe" % "{version}"

```

Finally, define your own type, which derives circe instances

```scala

import evo.derivation.*

import evo.derivation.circe.*

import evo.derivation.config.Config

import java.util.UUID

@SnakeCase

@Discriminator("type")

enum User derives Config, EvoCodec:

    case AuthorizedClient(@Rename("client_id") id: UUID, name: String)

    case Anonymous

```

## Annotation reference

### `@SnakeCase`

 Transforms all the constructor and\or field names to the snake case

### `@Discriminator(name: String)`

 Defines discriminator field for serialization of `sealed trait` or `enum`

### `@Rename(name: String)`

 Renames single `case class` field or `enum` constructor

### `@Embed`

Write\Reads all inner fields of some field on the upper level during serialization
