pub async fn fetch_positions_in_whirlpool(
rpc: &RpcClient,
whirlpool: Pubkey,
) -> Result<Vec<DecodedAccount<Position>>, Box<dyn Error>>
Expand description
Fetches all positions associated with a specific Whirlpool.
This function retrieves all positions linked to the given Whirlpool address using program filters. The positions are decoded and returned as a vector of hydrated position objects.
§Arguments
rpc
- A reference to the Solana RPC client.whirlpool
- The public key of the Whirlpool whose positions should be fetched.
§Returns
A Result
containing a vector of DecodedAccount<Position>
objects, representing the
positions associated with the given Whirlpool.
§Errors
This function will return an error if:
- RPC calls fail while fetching filtered accounts.
- Decoding the position data fails.
§Example
use orca_whirlpools::{
fetch_positions_in_whirlpool, set_whirlpools_config_address, WhirlpoolsConfigInput,
};
use solana_client::nonblocking::rpc_client::RpcClient;
use solana_sdk::pubkey::Pubkey;
use std::str::FromStr;
#[tokio::main]
async fn main() {
set_whirlpools_config_address(WhirlpoolsConfigInput::SolanaDevnet).unwrap();
let rpc = RpcClient::new("https://api.devnet.solana.com".to_string());
let whirlpool_address =
Pubkey::from_str("3KBZiL2g8C7tiJ32hTv5v3KM7aK9htpqTw4cTXz1HvPt").unwrap();
let positions = fetch_positions_in_whirlpool(&rpc, whirlpool_address)
.await
.unwrap();
println!("Positions: {:?}", positions);
