Struct HarnessCatalog

pub struct HarnessCatalog;

Expand description

Read-only entry point for discovering, loading, and following persisted harness sessions.

Implementations§

impl HarnessCatalog

pub fn new() -> HarnessCatalog

Construct a catalog. It holds no cache or global mutable state.

pub fn discover( &self, query: &DiscoveryQuery, ) -> Result<Vec<SessionDescriptor>, InterchangeError>

Discover sessions using lightweight headers/indexes rather than full transcript normalization. Malformed or concurrently-created entries are skipped without aborting the rest of the scan.

pub fn discover_page( &self, query: &DiscoveryQuery, ) -> Result<DiscoveryPage, InterchangeError>

Discover one stable page and return the cursor for its successor.

pub fn load( &self, locator: &SessionLocator, ) -> Result<Session, InterchangeError>

Load the complete normalized session named by a durable locator.

pub fn load_with_fidelity( &self, locator: &SessionLocator, fidelity: Fidelity, ) -> Result<Session, InterchangeError>

Self::load at a declared fidelity.

Read-only surfaces (a session mirror, follow) pass Fidelity::Semantic so a compacted transcript renders instead of erroring; every continuation/transfer/export caller keeps the strict default. See Session::load_with_fidelity.

pub fn follow( &self, locator: &SessionLocator, ) -> Result<SessionFollower, InterchangeError>

Open a passive change-triggered follower for a durable locator.

pub fn follow_with_fidelity( &self, locator: &SessionLocator, fidelity: Fidelity, ) -> Result<SessionFollower, InterchangeError>

Self::follow at a declared fidelity — see Self::load_with_fidelity.
