Looking for a specific Rust conf talk

I realise this is a long shot but I must try; Months a go I watched a Rust talk on youtube which was excellent and I'm trying to find it again. Problem is, all I can remember is that it was presented by a 30-40 something American lady with dark hair, and that it followed the idea of creating a basic RPG game to explain basic principles of Rust coding. It's not Catherine West's, Micah Tigley's or Sarah Meyer's.

Any clues? Thank you in advance.
