Struct Join 

pub struct Join {
    pub natural: bool,
    pub join_type: JoinType,
    pub outer: bool,
}

Builder for constructing JOIN clauses

This struct uses a builder pattern with const fn methods to allow compile-time construction of JOIN specifications.

Fields

natural: bool

join_type: JoinType

outer: bool

Implementations

impl Join

pub const fn new() -> Join

Creates a new Join with default settings (basic JOIN)

pub const fn natural(self) -> Join

Makes this a NATURAL join

pub const fn inner(self) -> Join

Makes this an INNER join

pub const fn left(self) -> Join

Makes this a LEFT join

pub const fn right(self) -> Join

Makes this a RIGHT join

pub const fn full(self) -> Join

Makes this a FULL join

pub const fn cross(self) -> Join

Makes this a CROSS join

pub const fn outer(self) -> Join

Makes this an OUTER join (LEFT OUTER, RIGHT OUTER, FULL OUTER)

Trait Implementations

impl Clone for Join

fn clone(&self) -> Join

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Join

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

Formats the value using the given formatter.

impl Default for Join

fn default() -> Join

Returns the “default value” for a type.

impl PartialEq for Join

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'a, V> ToSQL<'a, V> for Join

where V: SQLParam + 'a,

fn alias(&self, alias: &'static str) -> SQL<'a, V>
