An interface for queries to allow converting them to various database implementations

Required Methods

fn prepare_mysql<'life0, 'async_trait>( connection: &'life0 mut MySqlConnection, ) -> Pin<Box<dyn Future<Output = Result<MySqlStatement<'static>>> + Send + 'async_trait>>

where 'life0: 'async_trait,

MySQL version of Query::prepare.

fn query_mysql<'a>( &'a self, statement: &'a MySqlStatement<'static>, ) -> Query<'a, MySql, MySqlArguments>

MySQL version of Query::query.

fn row_data_mysql(row: &MySqlRow) -> Result<A>

MySQL version of Query::row_data.

Provided Methods

fn prepare<'life0, 'async_trait>( connection: &'life0 mut AnyConnection<'_>, ) -> Pin<Box<dyn Future<Output = Result<AnyStatement<'static>>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait,

Prepare a statement to be later used by Query::query.

fn query<'a>(&'a self, statement: &'a AnyStatement<'static>) -> AnyQuery<'a>

Get a query with all arguments bound already, ready to be fetched.

fn row_data(row: &AnyRow) -> Result<A>

Gets the row data for a result row of this query

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.
