Required Methods§

Source

fn execute<'life0, 'async_trait, T, V>( &'life0 self, wrapper: QueryWrapper<'static, T>, ) -> Pin<Box<dyn Future<Output = Result<V, Error>> + Send + 'async_trait>>
where T: DeserializeOwned + TableName + Send + Sync + 'static + 'async_trait, V: DeserializeOwned + 'async_trait, Self: 'async_trait, 'life0: 'async_trait,

Provided Methods§

Source

fn select_list<'life0, 'async_trait, T, V>( &'life0 self, wrapper: QueryWrapper<'static, T>, ) -> Pin<Box<dyn Future<Output = Result<Vec<T>, Error>> + Send + 'async_trait>>
where T: DeserializeOwned + TableName + Send + Sync + 'static + 'async_trait, V: DeserializeOwned + 'async_trait, Self: Sync + 'async_trait, 'life0: 'async_trait,

Source

fn select_one<'life0, 'async_trait, T, V>( &'life0 self, wrapper: QueryWrapper<'static, T>, ) -> Pin<Box<dyn Future<Output = Result<T, Error>> + Send + 'async_trait>>
where T: DeserializeOwned + TableName + Send + Sync + 'static + 'async_trait, V: DeserializeOwned + 'async_trait, Self: Sync + 'async_trait, 'life0: 'async_trait,

Source

fn select_count<'life0, 'async_trait, T, V>( &'life0 self, wrapper: QueryWrapper<'static, T>, ) -> Pin<Box<dyn Future<Output = Result<usize, Error>> + Send + 'async_trait>>
where T: DeserializeOwned + TableName + Send + Sync + 'static + 'async_trait, V: DeserializeOwned + 'async_trait, Self: Sync + 'async_trait, 'life0: 'async_trait,

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
