CreditCard Identifier - Rust

Credit Card BIN validation library using bin-cc data.

Installation

Add this to your Cargo.toml:

[dependencies]
creditcard-identifier = "2.1.0"

Usage

use creditcard_identifier::*;

fn main() {
    // Find brand
    let brand = find_brand("4012001037141112");
    println!("{:?}", brand); // Some("visa")
    
    // Check if supported
    let supported = is_supported("4012001037141112");
    println!("{}", supported); // true
    
    // Validate CVV
    let valid_cvv = validate_cvv("123", "visa");
    println!("{}", valid_cvv); // true
    
    // Luhn validation
    let valid_luhn = luhn("4012001037141112");
    println!("{}", valid_luhn); // true
}
