[−][src]Struct actix_session::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_session::Session; use actix_web::*; fn index(session: Session) -> Result<&'static str> { // access session data if let Some(count) = session.get::<i32>("counter")? { session.set("counter", count + 1)?; } else { session.set("counter", 1)?; } Ok("Welcome!") }
Methods
impl Session
[src]
pub fn get<T: DeserializeOwned>(&self, key: &str) -> Result<Option<T>, Error>
[src]

from the session.
pub fn set<T: Serialize>(&self, key: &str, value: T) -> Result<(), Error>
[src]
Set a value
from the session.
pub fn remove(&self, key: &str)
[src]
Remove value from the session.
pub fn clear(&self)
[src]
Clear the session.
pub fn set_session(
data: impl Iterator<Item = (String, String)>,
req: &mut ServiceRequest
)
[src]
data: impl Iterator<Item = (String, String)>,
req: &mut ServiceRequest
)
pub fn get_changes<B>(
res: &mut ServiceResponse<B>

Trait Implementations
impl FromRequest for Session
[src]
Extractor implementation for Session type.
use actix_session::Session; fn index(session: Session) -> Result<&'static str> { // access session data if let Some(count) = session.get::<i32>("counter")? { session.set("counter", count + 1)?; } else { session.set("counter", 1)?; } Ok("Welcome!") }
type Error = Error
The associated error which can be returned.
type Future = Result<Session, Error>
Future that resolves to a Self
type Config = ()

fn from_request(req: &HttpRequest, _: &mut Payload) -> Self::Future
[src]
fn extract(req: &HttpRequest) -> Self::Future
[src]

fn configure<F>(f: F) -> Self::Config where
F: FnOnce(Self::Config) -> Self::Config,
[src]
F: FnOnce(Self::Config) -> Self::Config,
