Cargo Features

[dependencies]
unicycle = { version = "0.10.2", default-features = false, features = ["parking-lot", "futures-rs"] }
default = futures-rs, parking-lot

These default features are set whenever unicycle is added without default-features = false somewhere in the dependency tree.

parking-lot default = lock_api, parking_lot
futures-rs default = futures-core

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.

futures-core futures-rs
parking_lot parking-lot
lock_api parking-lot
