Retry Utilities

use yldfi_common::{with_retry, RetryConfig, RetryableError};

// Implement RetryableError for your error type
impl RetryableError for MyError {
    fn is_retryable(&self) -> bool { true }
}

async fn example() {
    let config = RetryConfig::default();
    let result = with_retry(&config, || async {
        Ok::<_, MyError>("success")
    }).await;
}

Ethereum Utilities

use yldfi_common::eth::{is_valid_address, normalize_address};

assert!(is_valid_address("0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"));

Chain Mappings

use yldfi_common::chains::Chain;

let chain = Chain::from_id(1);
assert_eq!(chain, Chain::Ethereum);
assert_eq!(chain.name(), "ethereum");

Unit Conversions

use yldfi_common::units::{to_wei, from_wei};

// Convert 1.5 ETH to wei
let wei = to_wei("1.5", 18).unwrap();
