vibe.db.mongo.collection.MongoCollection.ensureIndex needs an ordered field_orders

[dcarp]

MongoDB uses JSON object values with ordered keys so that, for ensuring compound indexes, instead of following signature:

void ensureIndex(int[string] field_orders, IndexFlags flags = IndexFlags.None)

it will be necessary something like:

void ensureIndex(Tuple!(string, int)[] field_orders, IndexFlags flags = IndexFlags.None)

Unfortunately it is not so simple: on line 336 [1], a Bson dictionary is used that also has no key order defined.
Please reopen the issue.

[1] key[fo[0]] = Bson(fo[1]);

BSON AAs are ordered, so that should be fine.

I didn't know that! Thanks.
