Struct ScanIter 

pub struct ScanIter<'a, C: ?Sized, RV> { /* private fields */ }

An in-progress async scan iteration.

let mut iter = client.scan_match::<_, String>("prefix:*").await?;
while let Some(key) = iter.next_item().await {
    println!("{}", key?);
}

Implementations

impl<'a, C: CommandDispatch, RV: FromValkeyValue> ScanIter<'a, C, RV>

pub async fn next_item(&mut self) -> Option<ValkeyResult<RV>>

The next element, an error if fetching a page fails, or None if the scan completed. An error ends the iteration and subsequent calls return None.
