Cargo Features

i-utils has no features set by default.

[dependencies]
i-utils = { version = "1.0.0-beta.2", features = ["build"] }
build = proc-macro2, quote

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.
