Cargo Features

[dependencies]
rust_fixed_width = { version = "1.0.1", default-features = false, features = ["all"] }
default = all

The all feature is set by default whenever rust_fixed_width is added without default-features = false somewhere in the dependency tree.

all default = pad

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.
