Cargo Features

eventually-postgres = { version = "0.2.0", features = ["full", "with-tracing"] }
full = with-tracing
with-tracing full? = tracing, tracing-futures

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.
