Cargo Features

gmeta has no features set by default.

[dependencies]
gmeta = { version = "1.7.0", features = ["codegen"] }
codegen = gmeta-codegen

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.
