Cargo Features

StaticFraction has no features set by default.

[dependencies]
staticfraction = { version = "0.0.1", features = ["to_fraction"] }
to_fraction = fraction

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.
