Cargo Features

mmal-sys has no features set by default.

[dependencies]
mmal-sys = { version = "0.1.0-3", features = ["generate_bindings"] }
generate_bindings = bindgen

Enable this feature to automatically generate bindings for the mmal headers.
The default is to use the bindings already included in the src directory.

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.
