Cargo Features

uvc-sys has no features set by default.

[dependencies]
uvc-sys = { version = "0.2.0", features = ["vendor"] }
vendor = uvc-src

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.

uvc-src vendor?
