Cargo Features

[dependencies]
codes-iso-17442 = { version = "0.1.3", default-features = false, features = ["urn", "serde"] }

default = serde

The serde feature is set by default whenever codes-iso-17442 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.
