Cargo Features

tokio-condvar has no features set by default.

[dependencies]
tokio-condvar = { version = "0.3.0", features = ["all"] }
all = parking_lot

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.
