pub struct InitialReadBridge { /* private fields */ }

Implementations

impl InitialReadBridge

pub fn service_request( &self, command: BrowserServiceSessionCommand, wake: Option<WakeHandle>, ) -> Result<Receiver<Result<BrowserServiceSessionReply, String>>, String>

pub fn record( &self, app: &str, workspace: &str, checkout: &RecordCheckout, ) -> Result<Option<CommittedDocument>, RecordReadError>

The committed history checkout starts from, read before the app builds its record. None when no committed read answers it: the broker said the app’s own channel does (a record a sealed workspace does not hold yet, which is new and which the app makes there), and the record opens as one without a bridge would. A record the workspace sends this device only once it asks (crate::record::RecordId::arrives_on_demand) is asked for and never waited on: RecordReadError::Arriving until it is here, and the store’s readers are woken when it arrives. One the app’s own channel answers never arrives committed: it opens without a committed read too, rather than arriving forever.

pub fn answered_by_own_channel(&self, checkout: &RecordCheckout) -> bool

Whether the broker answered checkout’s read as the app’s own channel’s: a record a sealed workspace does not hold yet, which is new and which the app makes there. Never the primary route, which the bridge reads committed.
