Enum ParseMode 

#[non_exhaustive]
pub enum ParseMode {
    Isolated {
        path: PathBuf,
        source: WorkerSource,
    },
    InProcess {
        searched: Vec<PathBuf>,
    },
}

How an index run will parse.

The two modes produce identical graphs, which is exactly why the fallback went unnoticed: the worker is a pure isolation wrapper, so its absence costs nothing until a grammar abort()s and takes the whole run with it instead of skipping one file (#212). Reporting the mode is what makes the guarantee checkable at the moment it matters.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Isolated

Crash-isolated: parses run in a worker subprocess pool.

Fields

path: PathBuf

source: WorkerSource

InProcess

In-process: no worker was found, so a grammar crash aborts the run. Carries every location that was searched, so the warning can say where to put one.

Fields

searched: Vec<PathBuf>

Implementations

impl ParseMode

pub fn worker(&self) -> Option<&Path>

The worker binary to parse through, or None to parse in-process.

pub fn is_isolated(&self) -> bool

Whether parsing is crash-isolated.

pub fn summary(&self) -> String

One line naming the active mode, for gonzalo index to print.

pub fn warning(&self) -> Option<String>

The warning to emit when isolation is inactive, naming everywhere that was searched. None when parsing is isolated.
