Cargo Features

[dependencies]
contact-tracing = { version = "0.2.1", default-features = false, features = ["base64", "serde", "chrono"] }
default = chrono

The chrono feature is set by default whenever contact-tracing is added without default-features = false somewhere in the dependency tree.

base64 serde? = base64_
serde = base64, serde_

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.
