Add the following dependency to the Cargo.toml file:
[dependencies]
captcha-rs = "0.2.10"
And then get started in your main.rs
:
use captcha_rs::CaptchaBuilder;
fn main() {
let captcha = CaptchaBuilder::new()
.length(5)
.width(130)
.height(40)
.dark_mode(false)
.complexity(1) // min: 1, max: 10
.build();
println!("text: {}", captcha.text);
println!("base_img: {}", captcha.to_base64());
}
