ConfigDecoder instances

Iron provides ConfigDecoder instances for refined types:

import cats.syntax.all.*
import ciris.*

import io.github.iltotore.iron.*
import io.github.iltotore.iron.constraint.all.*
import io.github.iltotore.iron.cats.given
import io.github.iltotore.iron.ciris.given

type Username = String :| (Not[Blank] & MaxLength[32])
type Password = String :| (Not[Blank] & MinLength[9])

case class DatabaseConfig(username: Username, password: Secret[Password])

val databaseConfig: ConfigValue[Effect, DatabaseConfig] = (
  env("DB_USERNAME").as[Username],
  env("DB_PASSWORD").as[Password].secret
).mapN(DatabaseConfig.apply)
