Cargo Features

CiInfo has no features set by default.

[dependencies]
ci_info = { version = "0.14.14", features = ["serde-1"] }
serde-1 = serde, serde_derive

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.

serde serde-1?
serde_derive serde-1?
