//! Shared tokio runtime bridge for integration tests.
//!
//! `cargo test` runs `#[test]` fns concurrently on separate OS threads, so a per-call
//! `current_thread` Runtime would need one instance per caller. Instead this holds a single
//! process-wide `multi_thread` Runtime that tolerates concurrent `block_on()` callers, and every
//! test bridges into async code through it.
//!
//! Included into each integration-test binary via
//! `#[path = "../common/async_runtime.rs"] mod async_runtime;`.
