Cargo Features

[dependencies]
starship-alt = { version = "0.33.1", default-features = false, features = ["battery"] }
default = battery

The battery feature is set by default whenever starship-alt 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.

battery default

Enables battery

battery is optional (on by default) because the crate doesn't currently build for Termux see: https://github.com/svartalf/rust-battery/issues/33
