Cargo Features

[dependencies]
nu-ansi-term = { version = "0.50.3", default-features = false, features = ["std", "derive_serde_style", "gnu_legacy"] }
default = std

The std feature is set by default whenever nu-ansi-term is added without default-features = false somewhere in the dependency tree.

std default
derive_serde_style = serde
gnu_legacy

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.
