Cargo Features

[dependencies]
salty = { version = "0.3.0", default-features = false, features = ["slow-motion", "cose", "rustcrypto"] }
default = rustcrypto

The rustcrypto feature is set by default whenever salty is added without default-features = false somewhere in the dependency tree.

slow-motion
cose = cosey
rustcrypto default = ed25519

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.
