Cargo Features

[dependencies]
tweetnacly = { version = "0.2.0", default-features = false, features = ["fast"] }

default = fast

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

fast default = poly1305

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.
