Cargo Features

finder_info_bin has no features set by default.

[dependencies]
finder_info_bin = { version = "0.2.0", features = ["xattr"] }
xattr = libc

this feature enables the ability to read and write the FinderInfo xattr on MacOS.

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.
