Cargo Features

[dependencies]
string-intern = { version = "0.1.7", default-features = false, features = ["rustc-serialize", "serde"] }

default = rustc-serialize, serde

These default features are set whenever string-intern 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.
