Usage

use spdx::Expression;

fn main() {
    let this_is_fine = Expression::parse("MIT OR Apache-2.0").unwrap();

    assert!(this_is_fine.evaluate(|req| {
        if let spdx::LicenseItem::Spdx { id, .. } = req.license {
            // Both MIT and Apache-2.0 are OSI approved, so this expression
            // evaluates to true
            return id.is_osi_approved();
        }

        false
    }));

    assert!(!this_is_fine.evaluate(|req| {
        if let spdx::LicenseItem::Spdx { id, .. } = req.license {
            // This is saying we don't accept any licenses that are OSI approved
            // so the expression will evaluate to false as both sides of the OR
            // are now rejected
            return !id.is_osi_approved();
        }

        false
    }));

    // `NOPE` is not a valid SPDX license identifier, so this expression
    // will fail to parse
    let _this_is_not = Expression::parse("MIT OR NOPE").unwrap_err();
}
