Struct Sessions 

pub struct Sessions {
    state: Mutex<State>,
    sends: Mutex<HashMap<String, VecDeque<Instant>>>,
}

Fields

state: Mutex<State>

The open sessions and the packages being uninstalled, under one lock, so a session can’t open between an uninstall’s check and its prune.

sends: Mutex<HashMap<String, VecDeque<Instant>>>

Implementations

impl Sessions

fn state(&self) -> MutexGuard<'_, State>

pub fn begin_removal(&self, id: &str)

Ends every session of id and refuses new ones until Sessions::end_removal: an uninstall calls this before it deletes the widget’s data, so an open pane can’t write it back meanwhile.

pub fn end_removal(&self, id: &str)

Call once srv’s package list no longer has the widget, so no session can open for it from a stale list.

pub fn open( &self, packages: &[WidgetPackageInfo], id: &str, hash: &str, ) -> Result<String, AccessError>

A token for one pane of an approved package at hash.

pub fn close(&self, token: &str)

pub fn authorize( &self, packages: &[WidgetPackageInfo], token: &str, ) -> Result<(Session, WidgetPackageInfo), AccessError>

The session’s package, if it may still run: approved at the hash the session was opened for. An edited, re-approved, disabled or removed package ends every session of the old version.

pub fn take_send(&self, widget_id: &str) -> Result<(), AccessError>

Counts one agents.send for the package, or refuses it over the rate.

fn take_send_at(&self, widget_id: &str, now: Instant) -> Result<(), AccessError>
