Struct Context

pub struct Context<'ptr, 'req> {
    pub session_id: Uuid,
    /* private fields */
}

Context is a structure that is exposed to the programmer when registering closures as request handlers.

Fields

session_id: Uuid

Implementations

impl<'ptr, 'req> Context<'ptr, 'req>

pub fn new( request: Rc<RefCell<Request<'req>>>, response: Rc<RefCell<Response<'req>>>, session_id: Uuid, session_manager: Arc<SessionManager>, ) -> Self

pub fn request(&self) -> Ref<'_, Request<'req>>

Borrow the reference to the request.

pub fn request_mut(&mut self) -> RefMut<'_, Request<'req>>

Mutably borrow the reference to the request. This may be needed for what appears to be a read operation because items like headers and GET parameters are lazily parsed out of the request buffer.

pub fn response(&self) -> Ref<'_, Response<'req>>

Borrow the response that is to be sent back to the client.

pub fn response_mut(&mut self) -> RefMut<'_, Response<'req>>

Mutably borrow the response that is to be sent back to the client.

pub fn write_session(&self, session_id: Uuid, key: &str, value: &str) -> bool

Makes a write to a session with a key and value Returns true if a write happened to a session, false if no session id exists Writing an empty string to this will remove the item from the session storage

pub fn read_session(&self, session_id: Uuid, key: &str) -> Option<String>

Reads from a session store, the value associated with the key Returns None if the session or the key is nonexistent

pub fn clear_session(&self, session_id: Uuid)

Clears the session data of any session ID passed in Shrinks the session data hashmap accordingly

pub fn delete_session(&self, session_id: Uuid)

Completely deletes the session storage related to the passed-in session_id value Shrinks the session storage hashmap accordingly

pub fn new_session(&self) -> Uuid

Creates a new session and returns the session id zero uuid is the default invalid uuid

pub fn session_exists(&self, session_id: Uuid) -> bool

Returns true or false if the session associated with session_id exists

pub fn redirect(&mut self, location: &str)

Sets the response code and location header
