Package: @imqueue/core 3.3.2 — generated reference, not hand-written

Address of a cluster server, as supplied to the cluster membership operations [ICluster.add](https://imqueue.org/api/core/latest/core.icluster.add/), [ICluster.remove](https://imqueue.org/api/core/latest/core.icluster.remove/) and [ICluster.find](https://imqueue.org/api/core/latest/core.icluster.find/).

**Signature:**

```typescript
export interface IServerInput 
```

## Remarks

Servers are matched by `id` when both sides carry one, and by host and port otherwise. This is [IMessageQueueConnection](https://imqueue.org/api/core/latest/core.imessagequeueconnection/) without the credentials.
