Implementations

impl SqlJoin

pub fn to_mysql_join_clause<'a>(&self, s: &'a mut String) -> &'a str

Generate a JOIN clause for MySQL.

If real_table_name exists,

JOIN `<real_table_name>` AS `<other_table_name>` ON `<other_table_name>`.`<other_column_name>` = `<using_table_name>`.`<using_column_name>`

or

JOIN `<other_table_name>` ON `<other_table_name>`.`<other_column_name>` = `<using_table_name>`.`<using_column_name>`

pub fn format_mysql_join_clauses<'a>( joins: &[SqlJoin], s: &'a mut String, ) -> &'a str

Generate JOIN clauses for MySQL.

Concatenate a series of SqlJoins with \n.

Trait Implementations

impl Clone for SqlJoin

fn clone(&self) -> SqlJoin

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SqlJoin

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SqlJoin

fn eq(&self, other: &SqlJoin) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
