Cargo Features

crulz has no features set by default.

[dependencies]
crulz = { version = "0.0.7", features = ["compile"] }
compile = bincode, flate2

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.

bincode compile?
flate2 compile?
