Pool extension trait for additional query operations

Required Methods§

Source

fn insert<'life0, 'async_trait, T, P>( &'life0 self, entity: T, ) -> Pin<Box<dyn Future<Output = Result<P, Error>> + Send + 'async_trait>>
where T: SqlCommand + SqlParams + Send + Sync + 'static + 'async_trait, P: 'async_trait + for<'a> FromSql<'a> + Send + Sync, Self: 'async_trait, 'life0: 'async_trait,

Inserts a new record into the database

Source

fn update<'life0, 'async_trait, T>( &'life0 self, entity: T, ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>
where T: SqlCommand + UpdateParams + Send + Sync + 'static + 'async_trait, Self: 'async_trait, 'life0: 'async_trait,

Updates an existing record in the database

Source

fn delete<'life0, 'async_trait, T>( &'life0 self, entity: T, ) -> Pin<Box<dyn Future<Output = Result<u64, Error>> + Send + 'async_trait>>
where T: SqlCommand + SqlParams + Send + Sync + 'static + 'async_trait, Self: 'async_trait, 'life0: 'async_trait,

Deletes a record from the database

Source

fn fetch<'life0, 'async_trait, P, R>( &'life0 self, params: P, ) -> Pin<Box<dyn Future<Output = Result<R, Error>> + Send + 'async_trait>>
where P: SqlQuery<R> + SqlParams + Send + Sync + 'static + 'async_trait, R: FromRow + Send + Sync + 'static + 'async_trait, Self: 'async_trait, 'life0: 'async_trait,

Retrieves a single record from the database

Source

fn fetch_all<'life0, 'async_trait, P, R>( &'life0 self, params: P, ) -> Pin<Box<dyn Future<Output = Result<Vec<R>, Error>> + Send + 'async_trait>>
where P: SqlQuery<R> + SqlParams + Send + Sync + 'static + 'async_trait, R: FromRow + Send + Sync + 'static + 'async_trait, Self: 'async_trait, 'life0: 'async_trait,

Retrieves multiple records from the database

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.
