Enum JoinType 

pub enum JoinType {
    Inner,
    Left,
    Right,
    Full,
}

Types of joins supported for cross-table validation

Variants

Inner

Inner join - only rows that match in both tables

Left

Left join - all rows from left table, matching rows from right

Right

Right join - all rows from right table, matching rows from left

Full

Full outer join - all rows from both tables

Implementations

impl JoinType

pub fn to_sql(&self) -> &'static str

Convert to SQL join syntax

Trait Implementations

impl Clone for JoinType

fn clone(&self) -> JoinType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JoinType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for JoinType

fn eq(&self, other: &JoinType) -> 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 JoinType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
