-// [go.mongodb.org/mongo-driver/bson.Decoder]. To configure the empty interface
-// encode and decode behavior for a mongo.Client, use
-// [go.mongodb.org/mongo-driver/mongo/options.ClientOptions.SetBSONOptions].
-//
-// For example, to configure a mongo.Client to unmarshal BSON binary field
-// values as a Go byte slice, use:
-//
-// opt := options.Client().SetBSONOptions(&options.BSONOptions{
-// BinaryAsSlice: true,
