pub static PYSPY_BIN: Key<String>Expand description
Path to the py-spy binary. When non-empty, tried before
the fallback "py-spy" PATH lookup. See PS-3 in
introspect module doc.
Note: env var is PYSPY_BIN (not HYPERACTOR_MESH_PYSPY_BIN)
to preserve backward compatibility with existing deployments
that already set PYSPY_BIN.
