Rust library hcaptcha

The rust library hcaptcha is used with your backend service to verify the hcaptcha response provided from the client.

Installation

To use hcaptcha-rs in your project you can add the following to your Cargo.toml:

toml [dependencies] hcaptcha = "2.2.0"

Usage

Derive a validation method on the data structure representing your data, marking the captcha components in the data structure.

``` rust

use hcaptcha::Hcaptcha;

[derive(Debug, Deserialize, Hcaptcha)]

pub struct ContactForm { name: String, phone: String, email: String, message: String, #[captcha] token: String, } ```

Validate the captcha data.

``` rust # #[tokio::main] # async main() -> Result<(), Box> { let contactform: ContactForm = serdejson::fromstr(e.bodystring())?; contactform.validresponse(&secret, None).await?; # } # fn getyoursecret() -> String { # "0x123456789abcde0f123456789abcdef012345678".to_string() # }

```
