Struct ForeignKey 

pub struct ForeignKey {
    pub child_table: String,
    pub child_columns: Vec<String>,
    pub parent_table: String,
    pub parent_columns: Vec<String>,
    pub on_delete: Option<String>,
}

A foreign-key edge in a schema, returned by Connection::list_foreign_keys. The columns lists are aligned: child_columns[i] references parent_columns[i].

Fields

child_table: String

child_columns: Vec<String>

parent_table: String

parent_columns: Vec<String>

on_delete: Option<String>

Informational only: e.g. "CASCADE", "SET NULL", "NO ACTION". None when the backend doesn’t expose this (or it isn’t set).

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 Eq for ForeignKey

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.
