ENV VARs

• $RUC_LOG_LEVEL: log verbosity, INFO(default) or ERROR
  • any other value falls back to INFO
  • INFO lets info!/info_omit! print; ERROR suppresses them

  • bounds connect, handshake/authentication, and idle output draining
  • Default to 20s
  • The max value is 300s(5 minutes); larger values are clamped to 300
  • Unparsable values fall back to the default(20s)
• $RUC_HTTP_TIMEOUT: HTTP request timeout, in seconds
  • Default to 3s
  • The max value is 255s(u8::MAX)
  • Unparsable or out-of-range values fall back to the default(3s)
  • Read once at the first request, later changes have no effect
