Cargo Features

[dependencies]
async-tar = { version = "0.5.0", default-features = false, features = ["xattr"] }
default = xattr

The xattr feature is set by default whenever async-tar is added without default-features = false somewhere in the dependency tree.

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.
