Struct OptionalParserSupervisor 

pub struct OptionalParserSupervisor { /* private fields */ }

Synchronous owner of the one process-wide optional parser session.

Implementations

impl OptionalParserSupervisor

pub fn open(pack_root: impl AsRef<Path>) -> Result<Self, ParserSupervisorError>

Open and verify one installed immutable optional-parser artifact.

This performs no process creation. Unsupported hosts fail before artifact acquisition by higher layers, worker launch, or source transfer.

Errors

Returns a typed unsupported-host, path, manifest, payload, or digest error.

pub fn parse( &mut self, language_id: &str, source: &[u8], limits: ParserRequestLimits, absolute_deadline: Instant, no_progress_timeout: Duration, cancellation: &IndexCancellation, ) -> Result<ParserCompletionEvidence, ParserSupervisorError>

Parse bounded raw source through one grammar-affined contained worker.

absolute_deadline is never extended by progress. One pre-READY epoch covers currentness, reload, sealing, admission, and opening. A newly validated READY or later identity-validated advancing progress resets no_progress_timeout. cancellation is polled while waiting for admission, writes, and output.

Errors

Returns a typed artifact, grammar, containment, protocol, worker, cancellation, timeout, I/O, or mandatory cleanup failure. Any failed operation destroys the resident session before returning.

pub fn shutdown(&mut self) -> Result<(), ParserSupervisorError>

Close, drain, and reap the resident session when one exists.

Errors

Returns a typed cleanup failure when the direct child or an owned I/O thread cannot be verified as terminated within the cleanup deadline.
