import { PubSubBaseProtocol } from '@libp2p/pubsub'
import type { PubSubRPC, PublishResult, PubSubRPCMessage, PeerId, Message } from '@libp2p/interface'
import type { Uint8ArrayList } from 'uint8arraylist'

class MyPubsubImplementation extends PubSubBaseProtocol {
  decodeRpc (bytes: Uint8Array | Uint8ArrayList): PubSubRPC {
    throw new Error('Not implemented')
  }

  encodeRpc (rpc: PubSubRPC): Uint8Array {
    throw new Error('Not implemented')
  }

  encodeMessage (rpc: PubSubRPCMessage): Uint8Array {
    throw new Error('Not implemented')
  }

  async publishMessage (sender: PeerId, message: Message): Promise<PublishResult> {
    throw new Error('Not implemented')
  }
}
```
