Struct ParserPool 

pub struct ParserPool { /* private fields */ }

A pool of parse-worker subprocesses.

Implementations

impl ParserPool

pub fn new( worker_bin: impl Into<PathBuf>, size: usize, timeout: Duration, ) -> Self

Create a pool of size workers running worker_bin (the gonzalo-parse-worker binary), each parse bounded by timeout. Workers spawn lazily on first use.

pub fn with_worker_env(self, vars: Vec<(String, String)>) -> Self

Set extra environment variables handed to every spawned worker (on top of the inherited environment).

pub fn size(&self) -> usize

The number of worker slots.

pub async fn parse( &self, language: Language, source: &str, ) -> Result<CodeGraph, ParseError>

Parse source as language into a [CodeGraph] on an isolated worker. A worker crash is retried once on a fresh worker; a hang past the timeout is not retried (it may be pathological input that always hangs).
