Decoding data that is owned by Raydium Authority V4

Hello!

(I'm new to Solana blockchain)

I have a problem with finding schema for base64 encoded data field.I use websocket connection and subscribe to base vault address using accountSubscribe method.This vault account is owned by Raydium Authority V4.

Response looks like:

{"jsonrpc": "2.0","method": "accountNotification","params": {"result": {"context": {"slot": 298423747      },"value": {"data": ["ykGKaepGFLQHCirRxFiYQFSme+FyzCJg4Yt5R8zsSARBV7BYDzHF/ORKYlgtvPnXjudZQ6CEo5OzUDaNIomTCGAvdCo8RQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA","base64"        ],"owner": "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA","rentEpoch": 18446744073709551615,"lamports": 2039280,"executable": false,"space": 165      }    },"subscription": 16127  }}

I have tried to find any schema in github Raydium repositories, but nothing found, however found raydiym-idl, but I don't know how to use it in order to deserialize the bytes that I get after decoding data. I need an example how to do it in Rust.

Thanks
