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

## Installation

To use hcaptcha, add the following to your `Cargo.toml`:

```toml
[dependencies]
hcaptcha = "3.0.15"

```

## Breaking changes with version 3.0.0

- The `Hcaptcha` prefix has been removed from all types.
- The default feature now uses `rustls-backend` and not the `nativetls-backend`.
- The `verify_client_response` method has been deprecated in favour or the `verify` method.

## 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<dyn std::error::Error>> {
    let contact_form: ContactForm = serde_json::from_str(e.body_string())?;
    contact_form.valid_response(&secret, None).await?;
    # }
    # fn get_your_secret() -> String {
    #   "0x123456789abcde0f123456789abcdef012345678".to_string()
    # }

```

See the examples folder for an AWS Lambda contact form example.

## Web Assembly

Hcaptcha has been tested in a web assembly project using wasm-bindgen and node.

See the `hcaptcha-wasm` example for a sample project which can be run using `wasm-pack test --node`.
