pub type OnSpawnHook = Arc<dyn Fn(u32) + Send + Sync>;Expand description
Callback invoked once with the OS pid of the spawned agent subprocess.
Set via Agent::set_on_spawn_hook (or
crate::builder::AgentBuilder::on_spawn) so callers that need to
act on the running child — for example, updating a process registry
so zag ps kill self can SIGTERM the agent child instead of the
parent zag process — can capture the pid right after spawn and
before the terminal wait.
The callback fires once per spawn, with the pid of the direct
provider subprocess. On retries or resumes the callback fires again
for the new child. pid is not guaranteed to still be alive by the
time the callback runs; use the OS to confirm before signaling.
