Function bigml::wait::wait

pub async fn wait<T, E, F, R>(options: &WaitOptions, f: F) -> Result<T, E>where
    F: FnMut() -> R,
    R: Future<Output = WaitStatus<T, E>>,
    E: Display,
    Error: Into<E>,

Call f repeatedly, wait for it to return WaitStatus::Finished, an error, or a timeout. Honors WaitOptions.

use bigml::wait::{wait, WaitOptions, WaitStatus};
use anyhow::Error;

let value = wait::<_, anyhow::Error, _, _>(&WaitOptions::default(), || {
    async { WaitStatus::Finished("my value") }
}).await?;

assert_eq!(value, "my value");

If you return Ok(WaitStatus::Waiting) instead, this function will wait some number of seconds, and then try again.
