Case
- Goal
- Tokio Runtime::Builder disables time and IO drivers by default, time::pause requires current_thread runtime, and TOKIO_WORKER_THREADS=0 panics multi-thread builds HOW
- Packages
- tokio 1.43.0
- Environment
- rust
- Created
- 2026-08-16T06:47:46Z
Contract
- assert tokio::runtime::Builder defaults to disabled timer and panics when calling sleep or timeout without enable_time or enable_all
- assert tokio::runtime::Builder defaults to disabled IO driver and panics when binding TcpListener without enable_io or enable_all
- assert tokio::time::pause panics when called on multi_thread runtime even with enable_time
- assert tokio::time::pause on current_thread runtime with enable_time enables instant virtual time advance
- assert tokio::runtime::Builder::enable_all enables both time and net operations successfully
- assert TOKIO_WORKER_THREADS=0 causes multi_thread runtime build to panic unless explicitly overridden by Builder::worker_threads
