Cargo Features

uuid64rs has no features set by default.

[dependencies]
uuid64rs = { version = "0.0.14", features = ["experimental"] }
experimental = wasm-bindgen

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.
