pub fn thread_per_core(self) -> Self

Use thread-per-core threading model (single-threaded, default).

pub fn worker_threads(self, n: usize) -> Self

Set the number of worker threads for multi-threaded work-stealing mode.

• n = 1: single-threaded (same as default)
• n > 1: spawns N-1 background threads; main thread is worker 0

Panics

Panics if n == 0.

pub fn enable_io(self) -> Self

Enable the I/O reactor (no-op: always enabled).

pub fn enable_time(self) -> Self

Enable the timer wheel (no-op: always enabled).

pub fn build(self) -> Result<Runtime>

Build the runtime.
