Cargo Features

[dependencies]
backie = { version = "0.9.0", default-features = false, features = ["async_postgres"] }
default = async_postgres

The async_postgres feature is set by default whenever backie is added without default-features = false somewhere in the dependency tree.

async_postgres default = diesel-async

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
