case class ConcatCoercion(conf: SQLConf) extends Rule[LogicalPlan] with TypeCoercionRule with Product with Serializable

Coerces the types of Concat children to expected ones.

If spark.sql.function.concatBinaryAsString is false and all children types are binary, the expected types are binary. Otherwise, the expected ones are strings.
