Required Methods§

Source

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

Translate IndexCreateStatement into SQL statement.

Source

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

Translate TableRef into SQL statement.

Source

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

Translate IndexDropStatement into SQL statement.

Provided Methods§

Source

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".
