pub fn configured_worker_threads() -> Option<usize>Expand description
Resolve an explicit worker-thread count for the main runtime.
Returns None when unset or not a positive integer, so the default
one-worker-per-core behaviour is preserved. Reserving cores for non-Tokio
background work is the isolation lever the fast-Tokio guidance recommends
(“you rarely need every core for Tokio”); operators that co-locate VT Code
with other processes can lower this without rebuilding.
