Struct SessionData 

pub struct SessionData {
    pub id: String,
    pub data: HashMap<String, Value>,
    pub user_id: Option<i64>,
    pub csrf_token: String,

}

Session data container

Holds all session data including user authentication state and CSRF token.

Key-value data stored in the session

user_id: Option<i64>

Authenticated user ID (if any)

csrf_token: String

CSRF token for this session

dirty: bool

Whether the session has been modified

Implementations

impl SessionData

pub fn new(id: String, csrf_token: String) -> Self

Create a new session with the given ID

pub fn get<T: DeserializeOwned>(&self, key: &str) -> Option<T>

Get a value from the session

Example

let name: Option<String> = session.get("name");

pub fn put<T: Serialize>(&mut self, key: &str, value: T)

Put a value into the session

Example

session.put("name", "John");
session.put("count", 42);

pub fn forget(&mut self, key: &str) -> Option<Value>

Remove a value from the session

Returns the removed value if it existed.

pub fn has(&self, key: &str) -> bool

Check if the session has a key

pub fn flash<T: Serialize>(&mut self, key: &str, value: T)

Flash a value to the session (available only for next request)

Example

session.flash("success", "Item saved successfully!");

pub fn get_flash<T: DeserializeOwned>(&mut self, key: &str) -> Option<T>

Get a flashed value (clears it after reading)

pub fn age_flash_data(&mut self)

Age flash data (move new flash to old, clear old)

pub fn flush(&mut self)

Clear all session data (keeps ID and regenerates CSRF)

pub fn is_dirty(&self) -> bool

Check if the session has been modified

pub fn mark_clean(&mut self)

Mark the session as clean (after saving)
