Struct ForeignKey 

pub struct ForeignKey {
    pub columns: Vec<ColumnId>,
    pub references_table: TableId,
    pub references_columns: Vec<ColumnId>,
    pub on_update: ReferentialAction,
    pub on_delete: ReferentialAction,
}

A foreign key payload, attached to a Constraint of kind ConstraintKind::ForeignKey.

Fields

columns: Vec<ColumnId>

Local column IDs (ordered) that constitute the FK.

references_table: TableId

The table that this FK references.

references_columns: Vec<ColumnId>

Column IDs of the referenced primary/unique key, in matching order.

on_update: ReferentialAction

Action on parent UPDATE.

on_delete: ReferentialAction

Action on parent DELETE.

Trait Implementations

impl Clone for ForeignKey

fn clone(&self) -> ForeignKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ForeignKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ForeignKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ForeignKey

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
