Struct LocalPythonWorkerConfig 

pub struct LocalPythonWorkerConfig {
    pub python: PathBuf,
    pub runtime_root: Option<PathBuf>,
    pub manifest: PathBuf,
    pub handler_file: PathBuf,
    pub function: String,
    pub python_paths: Vec<PathBuf>,
    pub max_in_flight: usize,
    pub timeout: Duration,
}

Explicit local Python worker launch. The handler file is the direct digest-bound artifact; an optional environment binding checks deployment drift. A replay-safe descriptor additionally requires Linux, an unprivileged child, and a package on the read-only root filesystem. Bound paths reject links in their ancestry before canonicalization. On Windows, bound launches also retain read-share handles to inventoried files and configured path ancestors. Bound launches compile filesystem source modules without reading their bytecode caches.

Fields

python: PathBuf

Python executable or a trusted executable name resolved by the host environment. Environment-bound launches require a file path inside runtime_root.

runtime_root: Option<PathBuf>

Complete interpreter installation to check against the descriptor’s environment binding. Supply this together with python_environment; exclude the function manifest from it. On Windows, existing files and configured path ancestors remain guarded during supervision.

manifest: PathBuf

Canonical descriptor manifest consumed by the worker.

handler_file: PathBuf

Top-level Python module file containing the handler function.

function: String

Function name exported by handler_file.

python_paths: Vec<PathBuf>

Explicit import roots for the SDK and handler dependencies. The child does not inherit the host’s PYTHONPATH or Python user site.

max_in_flight: usize

Maximum simultaneous worker calls. The process and client use the same limit. The launcher sets OMP_NUM_THREADS=1 and OPENBLAS_NUM_THREADS=1 before imports.

timeout: Duration

Worker readiness and per-call deadline, between 1 millisecond and 30 seconds. Filesystem binding verification precedes the readiness deadline.

Trait Implementations

impl Clone for LocalPythonWorkerConfig

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
