Diesel feature flags missing from rocket_db_pools crate?

[Atlinx]

Hey all, I'm trying to use async Diesel with Rocket, and I noticed the diesel_postgres and diesel_mysql feature flags don't exist in the latest version, even though the documentation mentions being able to use these flags. Does this feature exist? If not, then what is the recommended way of setting up async Diesel with Rocket?

For now, I'm using a manual git import of the crate -- it seems like I was looking at the master version of the documentation, which may be documenting features that have not been released yet.

rocket_db_pools = { git = "https://github.com/SergioBenitez/Rocket", rev = "c2936fcb1e4f8f4907889b54a9e4e741a565a7d7", features = ["diesel_postgres"] }
