Enum JoinKind 

pub enum JoinKind {
    Inner,
    Left,
    Right,
    Full,
    Cross,
    Custom(Cow<'static, str>),
}

The join_type of a join.

Closed in the SQL standard, and left open at one point because MySQL’s STRAIGHT_JOIN sits in exactly this slot without being a standard join type. The OUTER in LEFT OUTER JOIN is noise — the standard makes it optional and means the same thing — so it is not spelled out.

Variants

Inner

INNER JOIN. The default, matching SQL’s own default for a bare JOIN.

Left

LEFT JOIN.

Right

RIGHT JOIN.

Full

FULL JOIN.

Cross

CROSS JOIN, which takes neither ON nor USING.

Custom(Cow<'static, str>)

A dialect’s own join keyword, written verbatim — MySQL’s STRAIGHT_JOIN.
