Cargo Features

audiopus_sys has no features set by default.

audiopus_sys = { version = "0.2.2", features = ["dynamic", "static", "generate_binding"] }
generate_binding = bindgen

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.
