Cargo Features

[dependencies]
hyperion = { version = "0.2.1", default-features = false, features = ["grammar"] }
default = grammar

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

grammar default = nom

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.
