pub fn ssh_worker_binary_prerequisite(
template: &TargetTemplate,
executor: &impl CommandExecutor,
) -> Option<(String, Result<WorkerBinaryAvailability>)>Expand description
The worker an existing SSH host needs, with the target triple it is
named by, read from the host’s own platform. None for a template that
is not a bare SSH host and for a host that does not say what it runs; the
SSH reachability check reports the latter.
