Cargo Features

[dependencies]
aquatic_peer_id = { version = "0.9.0", default-features = false, features = ["quickcheck"] }
default = quickcheck

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

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.
