Required Methods§

Source

fn publish<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, channel: &'life1 str, message: &'life2 [u8], ) -> Pin<Box<dyn Future<Output = StorageResult<usize>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Publish message to channel

Source

fn subscribe<'life0, 'life1, 'async_trait>( &'life0 self, channel: &'life1 str, ) -> Pin<Box<dyn Future<Output = StorageResult<Box<dyn Subscriber>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Subscribe to channel

Source

fn unsubscribe<'life0, 'life1, 'async_trait>( &'life0 self, channel: &'life1 str, ) -> Pin<Box<dyn Future<Output = StorageResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Unsubscribe from channel

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
