Required Methods

fn create(&self, key: &ConnectionKey) -> Box<dyn Connection>

fn is_alive(&self) -> bool

fn open<'life0, 'life1, 'async_trait>( &'life0 mut self, params: &'life1 ResolvedConnectionParams, ) -> Pin<Box<dyn Future<Output = Result<(), String>> + Send + 'async_trait>>

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

fn close(&mut self) -> ConnectionKey

Provided Methods

fn execute_command<'life0, 'life1, 'async_trait>( &'life0 mut self, _command: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<String, String>> + Send + 'async_trait>>

Dyn Compatibility

This trait is dyn compatible.

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