Provided Methods

fn set_custom_value_no_read<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 [u8], value: Vec<u8>, ) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Put arbitrary data into the custom store, do not attempt to read any previous data

Optimization option for set_custom_values for stores that would perform better withouts the extra read and the caller not needing that data returned. Otherwise this just wraps around set_custom_data and discards the result.

Arguments

• key - The key to insert data into

• value - The value to insert
