Struct SessionMemoryOverlay 

pub struct SessionMemoryOverlay { /* private fields */ }

The searchable projection of the session ledger.

Implementations

impl SessionMemoryOverlay

pub fn new() -> Self

An empty overlay.

pub fn revision(&self) -> u64

Overlay revision, bumped on every rebuild that changed something.

pub fn index(&self) -> &MemoryIndex

The searchable index.

pub fn len(&self) -> usize

How many facts the overlay holds.

pub fn is_empty(&self) -> bool

Whether the overlay is empty.

pub fn rebuild( &mut self, owner: &UserId, session_id: &SessionId, candidates: &[SessionCandidate], now: DateTime<Utc>, ) -> usize

Rebuild from the ledger’s usable candidates.

Rebuilding wholesale rather than patching is what makes suppression work: a candidate contradicted this turn simply stops being produced, and cannot linger in the index asserting the old value.

pub fn clear(&mut self)

Drop every overlay fact, e.g. when a logical session ends.

impl Debug for SessionMemoryOverlay

fn fmt(&self, f: &mut Formatter<'_>) -> Result
