This example shows how to selectively allow certain licenses that will be checked against the license requirements of every crate in your dependency graph.
license = "MIT OR Apache-2.0"
[license] allow = [ "MIT" ]
The example crate uses the same dual-licensing of the actual cargo-deny project, namely MIT OR Apache-2.0, and this expression is checked against our configured allow list, which is simply MIT. This license check passes because the license expression allows you to license it under either MIT or Apache-2.0 at your option.
