Enum ManagedExecutable 

pub enum ManagedExecutable {
    CurrentServer,
    Path(PathBuf),
}

The executable a managed worker instance launches.

Variants

CurrentServer

This server’s own binary, resolved through the operating system at each spawn. The production choice, and the only one a builtin artifact reference can mean.

Path(PathBuf)

An explicit executable path. The seam supervision tests drive, so a test never risks re-executing the test binary itself.

Implementations

impl ManagedExecutable

pub fn resolve(&self) -> Result<PathBuf, SupervisionError>

Resolve the path to launch.

Errors

Returns SupervisionError::ExecutableUnresolved when the operating system cannot identify this server’s own executable.

pub fn identify(&self, path: &Path) -> Result<SpawnedBinary, SupervisionError>

Capture the identity of path as this spawn will run it.

The build stamp is reported only for this server’s own binary: it is the only executable whose version and commit this process actually knows.

Errors

Returns SupervisionError::ExecutableUnreadable when the bytes cannot be read, which is also the honest report for a deployment naming a path that no longer exists.
