.open?(key: nil, if: nil, close_if: nil, close_if_reach_limit: nil, limit_count: nil, initially_closed: nil) ⇒ Boolean

Syntax sugar for ‘CircuitSwitch.run`

Parameters:

  • key (String) (defaults to: nil) —

    Named key to find switch instead of caller

  • if (Boolean, Proc) (defaults to: nil) —

    ‘CircuitSwitch.run` is runnable when `if` is truthy (default: true)

  • close_if (Boolean, Proc) (defaults to: nil) —

    ‘CircuitSwitch.run` is runnable when `close_if` is falsy (default: false)

  • close_if_reach_limit (Boolean) (defaults to: nil) —

    ‘CircuitSwitch.run` is NOT runnable when run count reaches limit (default: true)

  • limit_count (Integer) (defaults to: nil) —

    Limit count. Use ‘run_limit_count` default value if it’s nil. Can’t be set 0 (default: nil)

  • initially_closed (Boolean) (defaults to: nil) —

    Create switch with terminated mode (default: false)

Returns:

  • (Boolean)

Parameters:

  • key (String) (defaults to: nil) —

    Named key to find switch instead of caller

  • if (Boolean, Proc) (defaults to: nil) —

    Report when ‘if` is truthy (default: true)

  • stop_report_if (Boolean, Proc) (defaults to: nil) —

    Report when ‘close_if` is falsy (default: false)

  • stop_report_if_reach_limit (Boolean) (defaults to: nil) —

    Stop reporting when reported count reaches limit (default: true)

  • limit_count (Integer) (defaults to: nil) —

    Limit count. Use ‘report_limit_count` default value if it’s nil Can’t be set 0 when ‘stop_report_if_reach_limit` is true (default: nil)
