Cargo Features

nu-ansi-term has no features set by default.

nu-ansi-term = { version = "0.50.0", features = ["derive_serde_style", "gnu_legacy"] }
derive_serde_style = serde

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.
