Cargo Features

Robust has no features set by default.

[dependencies]
robust = { version = "1.1.0", features = ["no_std"] }
no_std = ieee754

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.
