Struct actix_web::dev::ExtractorConfig

pub struct ExtractorConfig<S: 'static, T: FromRequest<S>> { /* fields omitted */ }

Extractor configuration

Route::with() and Route::with_async() returns instance of the ExtractorConfig type. It could be used for extractor configuration.

In this example Form<FormData> configured.

#[macro_use] extern crate serde_derive;
use actix_web::{App, Form, Result, http};

#[derive(Deserialize)]
struct FormData {
    username: String,
}

fn index(form: Form<FormData>) -> Result<String> {
    Ok(format!("Welcome {}!", form.username))
}

fn main() {
    let app = App::new().resource(
       "/index.html", |r| {
           r.method(http::Method::GET)
             .with(index)
             .limit(4096);} // <- change form extractor configuration
    );
}

Same could be donce with multiple extractors

#[macro_use] extern crate serde_derive;
use actix_web::{App, Form, Path, Result, http};

#[derive(Deserialize)]
struct FormData {
    username: String,
}

fn index(data: (Path<(String,)>, Form<FormData>)) -> Result<String> {
    Ok(format!("Welcome {}!", data.1.username))
}

fn main() {
    let app = App::new().resource(
       "/index.html", |r| {
           r.method(http::Method::GET)
             .with(index)
             .1.limit(4096);} // <- change form extractor configuration
    );
}
