Cargo Features

[dependencies]
chinese-number = { version = "0.7.7", default-features = false, features = ["std", "number-to-chinese", "chinese-to-number"] }
default = chinese-to-number, number-to-chinese, std

These default features are set whenever chinese-number is added without default-features = false somewhere in the dependency tree.

std default
number-to-chinese default = num-bigint, num-traits
chinese-to-number default = num-traits

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.

num-bigint number-to-chinese
num-traits chinese-to-number number-to-chinese
