Cargo Features

Fastant has no features set by default.

[dependencies]
fastant = { version = "0.1.9", features = ["atomic", "fallback-coarse"] }
atomic
fallback-coarse = coarsetime

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.
