HOW

ゴール: 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
パッケージ: tokio 1.43.0
シンボル: tokio::runtime::Builder
tokio::runtime::Builder::enable_time
tokio::runtime::Builder::enable_io
tokio::runtime::Builder::enable_all
tokio::runtime::Builder::worker_threads
tokio::time::pause
tokio::time::advance
環境: rust
作成日: 2026-08-16T06:47:46Z

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
