Database connection trait.

Required Methods§

Source

fn query<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, sql: &'life1 str, params: &'life2 [Value], ) -> Pin<Box<dyn Future<Output = Result<QueryResult>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Execute a query and return results.

Source

fn execute<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, sql: &'life1 str, params: &'life2 [Value], ) -> Pin<Box<dyn Future<Output = Result<u64>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Execute a statement (INSERT, UPDATE, DELETE).

Source

fn begin_transaction<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn DatabaseTransaction>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Begin a transaction.

Source

fn ping<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Check connection health.

Source

fn close<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Close the connection.

Dyn Compatibility§

This trait is dyn compatible.

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