    // Required methods
    fn prepare_index_create_statement(

        create: &IndexCreateStatement,

    // Provided method
    fn prepare_table_index_expression(
        &self,
        create: &IndexCreateStatement,
        sql: &mut impl SqlWriter,
    ) { ... }
}

Required Methods§

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

Translate IndexCreateStatement into SQL statement.

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

Translate TableRef into SQL statement.

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

Translate IndexDropStatement into SQL statement.

Provided Methods§

fn prepare_table_index_expression( &self, create: &IndexCreateStatement, sql: &mut impl 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 not dyn compatible.

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