In Uniswap V3, retrieving the pool's current price (sqrtPriceX96) was straightforward using the slot0() function from the pool contract:

 let pool_instance = get_pool_contract(
   factory_address, 
   nft_pos_return.token0, 
   nft_pos_return.token1, 
   FeeAmount::from(nft_pos_return.fee), 
   provider.clone()
  );
let slot0_opt = pool_instance.slot0().call().await.unwrap();

However, in Uniswap V4, the architecture has changed, and this functionality is now handled via external libraries such as:

• StateLibrary.get ( Docs )
• Extsload ( Docs )

Since these are Solidity libraries rather than contract functions, calling them directly from Rust is not as straightforward.

My Question: Is there a way to retrieve the current pool price (sqrtPriceX96) from Rust without having to write custom Solidity contracts?

Unfortunately, the existing Rust SDK for Uniswap V4 (uniswap-v4-sdk) does not yet cover all required functionality.

Has anyone successfully fetched sqrtPriceX96 from Uniswap V4 using Rust, and if so, what approach did you take? Any insights or workarounds would be greatly appreciated!
