where
    S: CaptchaStorage,
    F: CaptchaFinder,
{ /* private fields */ }

The captcha middleware

The captcha middleware is used to check the captcha token and answer from the request. You can use the CaptchaBuilder to create a new captcha middleware.

Note

You need to generate the captcha token and answer before, then the captcha middleware will check the token and answer from the request using the finder and storage you provided. The captcha middleware will insert the CaptchaState into the depot, you can get the captcha state from the depot using the CaptchaDepotExt::get_captcha_state trait, which is implemented for the Depot.

Check the examples for more information.
