Enum WorkerSource 

#[non_exhaustive]
pub enum WorkerSource {
    Env,
    Sibling,
    Path,
}

Where a parse worker was found.

#[non_exhaustive]: this set is already known to be growing — #212’s own proposal anticipates a --parse-worker <path> flag, which is a fourth source. Sealing it now costs nothing; adding a variant later to a sealed enum is not a breaking change, while adding one to an open enum is (#241).

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.

Env

The GONZALO_PARSE_WORKER environment override.

Sibling

Beside the running executable (the installed / cargo build layout).

Path

On PATH — the symlink and split-install layouts, where a sibling check cannot succeed but the worker is plainly available.
