Cargo Features

libmpv-sys-sirno has no features set by default.

[dependencies]
libmpv-sys-sirno = { version = "2.0.0-fork.1", features = ["use-bindgen"] }
use-bindgen = bindgen

You can either use the pregenerated bindings, or gen new ones with 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.
