Struct Join 

pub struct Join {
    pub join_type: JoinType,
    pub table: String,
    pub left_column: String,
    pub right_column: String,
}

A JOIN clause specifying which table to join and on which columns.

Fields

join_type: JoinType

The type of join (INNER, LEFT, RIGHT, FULL).

table: String

The table to join with.

left_column: String

Column on the left side of the ON condition. Qualified (“users.id”) or unqualified (“id”, defaults to FROM table).

right_column: String

Column on the right side of the ON condition. Qualified (“posts.user”) or unqualified (“user”, defaults to joined table).

Implementations

impl Join

pub fn inner(table: &str, left_column: &str, right_column: &str) -> Self

Creates an INNER JOIN.

pub fn left(table: &str, left_column: &str, right_column: &str) -> Self

Creates a LEFT JOIN.

pub fn right(table: &str, left_column: &str, right_column: &str) -> Self

Creates a RIGHT JOIN.

pub fn full(table: &str, left_column: &str, right_column: &str) -> Self

Creates a FULL OUTER JOIN.

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Join

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 Serialize for Join

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Join

impl StructuralPartialEq for Join
