This crate provides an easy way to validate an IBAN (International Bank Account Number). To do so, you can use the function parse(). This will check the IBAN rules as well as the BBAN structure. The provided Iban structure provides many methods to easy the handling of an IBAN. Many of these methods are provided via the IbanLike trait.
When BBAN parsing fails, the error type ParseIbanError provides useful information about what went wrong. Additionally, the error contains BaseIban, which can still be used to access useful information.
The following example does a full validation of the IBAN and BBAN format.
use iban::*;
fn main() -> Result<(), ParseIbanError> {
let account = "DE44500105175407324931".parse::<Iban>()?;
assert_eq!(account.country_code(), "DE");
assert_eq!(account.check_digits(), 44);
assert_eq!(account.bban(), "500105175407324931");
// The electronic format is also returned through `Debug::fmt`
assert_eq!(account.electronic_str(), "DE44500105175407324931");
// The pretty 'paper' format can be obtained via `Display::fmt`
assert_eq!(account.to_string(), "DE44 5001 0517 5407 3249 31");
assert_eq!(account.bank_identifier(), Some("50010517"));
assert_eq!(account.branch_identifier(), None);
Ok(())
}- A
Ibantype that can be used to parse account numbers very quickly. It doesn't require allocations at all, and instead leveragesarrayvecunder the hood. - A flexible API that is useful even when the country is not in the Swift registry (using
BaseIban). Instead of using panic, the crate provides typed errors with what went wrong. - All functionality can be used in a
no_stdenvironment. - Optional serialization and deserialization via
serde. - CI tested results via the Swift provided and custom test cases, as well as proptest.

This crate is usable on the latest stable release of the Rust compiler and adheres to semver. The IBAN registry may be updated with patch releases, because of this results may differ even between patch versions.
