Enum QueryData

pub enum QueryData<T, E> {
    Loading,
    Ok(T),
    Err(E),
}

Expand description

The data type of a query.

§States

Loading - No query data is available yet
Ok - Query data was successfully fetched and is available. Note this might be stale data, check QueryStatus if you need to verify whether the query is currently fetching fresh data.
Err - Query data still wasn’t able to be fetched after the retry strategy was exhausted. This contains the backing error.

Variants§

Loading

No query data is available yet

Ok(T)

Query data was successfully fetched and is available. Note this might be stale data, check QueryStatus if you need to verify whether the query is currently fetching fresh data.

Err(E)

Query data still wasn’t able to be fetched after the retry strategy was exhausted. This contains the backing error.
