Struct SessionSlot 

pub struct SessionSlot { /* private fields */ }

Shared between all clones of one server; the live instance is replaced only on a project change.

Implementations

impl SessionSlot

pub fn new(session: SharedSession) -> Self

pub fn remember_own(&self, project_root: &str, session_id: &str)

Record that this server’s session for project_root is session_id.

pub fn own_session_id(&self, project_root: &str) -> Option<String>

The session this server left project_root with, if any.

pub fn live(&self) -> SharedSession

The instance new requests bind to, ignoring any request binding.

pub fn instance(&self) -> SharedSession

The instance this request is bound to, or the live one outside a bound request.

pub async fn read(&self) -> OwnedRwLockReadGuard<SessionState>

pub async fn write(&self) -> OwnedRwLockWriteGuard<SessionState>

pub fn replace_if_live( &self, current: &SharedSession, next: SharedSession, ) -> bool

Install next as the live instance if current still is it. Requests already bound keep the previous one. false: another switch won.

pub fn rebind(&self, next: SharedSession)

Move the current request’s binding to next: a request that switched the session itself continues in the new one. No-op outside a bound request.

pub async fn scope<F: Future>(&self, request: F) -> F::Output

Run one request with an empty binding; Self::pin fills it.

A request that ends bound to an instance no longer live saves its late changes there, under that session’s own project: the batch cadence that would otherwise pick them up only runs on the live instance.

pub fn pin(&self)

Bind the current request to the live instance once its roots are resolved. A request keeps its first binding; outside Self::scope this is a no-op.

Trait Implementations

impl Clone for SessionSlot

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
