pub const WORKER_READY_MARKER_OVERRIDE_ENV: &str = "KTSTR_WORKER_READY_MARKER_OVERRIDE";Expand description
Name of the test-only env var that overrides the pid-scoped
default path. When set and non-empty, the worker writes the
ready marker at the override path instead of
worker_ready_marker_path(pid);
when unset (or empty) the default pid-scoped path applies.
Exported as a pub const so both the worker binary and the
integration tests that drive it share a single source of truth
— eliminating the string-literal drift window where the worker
and a test disagree on the env-var name and the override
silently fails to take effect.
