Required Methods§

Source

fn write<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, value: String, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Write value to this instance’s key slot (overwrites).

Source

fn read_from<'life0, 'life1, 'async_trait>( &'life0 self, who: NodeId, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Option<String>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Read key from who’s slot.

Source

fn scan<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Vec<(NodeId, String)>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Every visible instance’s value for key.
