Source

pub fn new() -> Self

Create a new ValidatorMiddleware to put in your tide configuration.

§Example

fn main() -> io::Result<()> {
    task::block_on(async {
        let mut app = tide::new();

        let mut validator_middleware = ValidatorMiddleware::new();
        validator_middleware.add_validator(HttpField::Header("X-Custom-Header"), is_number);

        app.at("/test/:n").middleware(validator_middleware).get(
            |_: tide::Request<()>| async move { Ok(tide::Response::new(StatusCode::Ok).body_json("test").unwrap()) },
        );

        app.listen("127.0.0.1:8080").await?;
        Ok(())
    })
}

pub fn with_validators<F>( self, validators: HashMap<HttpField<'static>, F>, ) -> Self
where F: Fn(&str, Option<&str>) -> Result<(), T> + Send + Sync + 'static,

Source

pub fn add_validator<F>(&mut self, param_name: HttpField<'static>, validator: F)
where F: Fn(&str, Option<&str>) -> Result<(), T> + Send + Sync + 'static,

Add new validator for your middleware

§Example

fn main() -> io::Result<()> {
    task::block_on(async {
        let mut app = tide::new();

        let mut validator_middleware = ValidatorMiddleware::new();
        validator_middleware.add_validator(HttpField::Header("X-Custom-Header"), is_number);
        validator_middleware.add_validator(HttpField::QueryParam("myqueryparam"), is_required);

        app.at("/test/:n").middleware(validator_middleware).get(
            |_: tide::Request<()>| async move { Ok(tide::Response::new(StatusCode::Ok).body_json("test").unwrap()) },
        );

        app.listen("127.0.0.1:8080").await?;
        Ok(())
    })
