Struct actix_web::middleware::session::Session

pub struct Session(_);

The high-level interface you use to modify session data.

Session object could be obtained with RequestSession::session method. RequestSession trait is implemented for HttpRequest.

use actix_web::middleware::session::RequestSession;
use actix_web::*;

fn index(mut req: HttpRequest) -> Result<&'static str> {
    // access session data
    if let Some(count) = req.session().get::<i32>("counter")? {
        req.session().set("counter", count + 1)?;
    } else {
        req.session().set("counter", 1)?;
    }

    Ok("Welcome!")
}
