Example usage
// Validate an IBAN
var ok = Finance.Iban.TryValidate("FR14 2004 1010 0505 0001 3M02 606", out var iban);
Console.WriteLine(ok); // True
Console.WriteLine(iban.Value!.Value); // FR1420041010050500013M02606
// Generate a GTIN-13
foreach (var s in Bulk.GenerateMany((dst, rng) => {
var ok = Logistics.Gtin.TryGenerate(13, new GenerationOptions { Seed = rng.Next() }, dst, out var w);
return (ok, w);
}, count: 3, seed: 42))
{
Console.WriteLine(s);
}
// Validate a telecom identifier
var imeiOk = Telecom.Imei.TryValidate("490154203237518", out var imei);

Contributing
See contributors.md for guidelines. In short, fork the repository, create a topic branch, and open a pull request:
Describe the motivation and design in the PR description.
Ensure tests and formatting checks pass.
The maintainers will review and merge when ready.
Continuous integration via GitHub Actions restores dependencies, builds, and runs the test suite on every push and pull request. Packages are produced by the publish workflow and releases are drafted automatically.
