Cargo Features

[dependencies]
uuid-mc = { version = "0.3.0", default-features = false, features = ["offline", "online"] }
default = offline, online

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

offline default = md5
online default = ureq

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.
