Rust Raydium Swap

There is a bot on Rust. It copies wallet transactions in the Solana network.

What exactly I need:

Implement the swap for buying raydium, implement the swap for selling raydium, use as few RPC requests as possible to maintain the speed of the bot. 

Improve/accelerate the current raydium transaction parsing if possible.

Currently, the bot receives data via gRPC in raw form, roughly speaking. 

I have already implemented a rough transaction parser, I need to know this data:

transaction executor

amount of tokens (with decimals)

amount of solana

path (whether it is a purchase or a sale)

and of course the token address

I need to implement the raydium transaction parsing and instructions for the swap. 

There is already some initial code, I can show you a private repository on Git.
