Cargo Features

[dependencies]
iso = { version = "0.0.10", default-features = false, features = ["std", "serde-std", "country", "language"] }
default = country, language, std

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

std default
serde-std

Enables std of serde

serde:

Provide impls for common standard library types like Vec<T> and HashMap<K, V>.
Requires a dependency on the Rust standard library.

country default

language default

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.
