Mapping from a BSON string to T;
Used by scala.collection.Map handlers.
final class Foo(val v: String) extends AnyVal
val bson = reactivemongo.api.bson.BSONDocument(
"foo:key" -> 1, "foo:name" -> 2)
import reactivemongo.api.bson.KeyReader
implicit def fooKeyReader: KeyReader[Foo] =
KeyReader[Foo] { str =>
new Foo(str.stripPrefix("foo:"))
}
reactivemongo.api.bson.BSON.readDocument[Map[Foo, Int]](bson)
// Success: Map[Foo, Int](
// (new Foo("key") -> 1),
// (new Foo("name") -> 2))
