Cargo Features

aptos-time-service has no features set by default.

aptos-time-service = { version = "0.2.7", features = ["async", "testing"] }
async testing? = futures, pin-project, tokio
testing = async

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.

futures async?
pin-project async?
tokio async?
