    // Required methods
    fn prepare_index_create_statement(

        create: &IndexCreateStatement,

    // Provided method
    fn prepare_table_index_expression(

    ) { ... }
}

Required Methods§

fn prepare_index_create_statement( &self, create: &IndexCreateStatement, sql: &mut dyn SqlWriter, )

Translate IndexCreateStatement into SQL statement.

fn prepare_table_ref_index_stmt( &self, table_ref: &TableRef, sql: &mut dyn SqlWriter, )

Translate TableRef into SQL statement.

fn prepare_index_drop_statement( &self, drop: &IndexDropStatement, sql: &mut dyn SqlWriter, )

Translate IndexDropStatement into SQL statement.

Provided Methods§

fn prepare_table_index_expression( &self, create: &IndexCreateStatement, sql: &mut dyn SqlWriter, )

Translate IndexCreateStatement into SQL expression. This is the default implementation for PostgresQueryBuilder and SqliteQueryBuilder. MysqlQueryBuilder overrides this default implementation.

Dyn Compatibility§

This trait is dyn compatible.

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