### 運行

使用以下指令運行伺服器：

<div class="termy">

```console
$ uvicorn main:app --reload

  class AddressState(
    val address: Address,
    val queue: TaskQueue,
    var policy: AddressPolicy,
  ) {
    /**
     * How many calls the pool can carry without opening new connections. This field must only be
     * accessed by the connection closer task.

    var concurrentCallCapacity: Int = 0
