Function retry 

pub async fn retry<T, F, R>(retry_future: F) -> Result<R, Error>
where
    F: FnMut() -> T,
    T: Future<Output = Result<R, Error>>,

Retry a future until it doesn’t return a disconnected error.

Example

use subxt::backend::utils::retry;

async fn some_future() -> Result<(), subxt::error::Error> {
   Ok(())
}

#[tokio::main]
async fn main() {
   let result = retry(|| some_future()).await;
}
