Struct ForeignKey 

pub struct ForeignKey {
    pub database: Option<Cow<'static, str>>,
    pub table: Cow<'static, str>,
    pub name: Cow<'static, str>,
    pub columns: Vec<Cow<'static, str>>,
    pub foreign_database: Option<Cow<'static, str>>,
    pub foreign_table: Cow<'static, str>,
    pub foreign_columns: Vec<Cow<'static, str>>,
    pub on_delete: Option<ReferentialAction>,
    pub on_update: Option<ReferentialAction>,
}

A foreign key from table(columns) to foreign_table(foreign_columns).

Fields

table: Cow<'static, str>

name: Cow<'static, str>

columns: Vec<Cow<'static, str>>

foreign_database: Option<Cow<'static, str>>

Database of the referenced table; None for the current database.

foreign_table: Cow<'static, str>

foreign_columns: Vec<Cow<'static, str>>

on_delete: Option<ReferentialAction>

ON DELETE action; None when not written.

on_update: Option<ReferentialAction>

ON UPDATE action; None when not written.

Implementations

impl ForeignKey

pub fn new( table: impl Into<Cow<'static, str>>, name: impl Into<Cow<'static, str>>, columns: impl IntoIterator<Item = impl Into<Cow<'static, str>>>, foreign_table: impl Into<Cow<'static, str>>, foreign_columns: impl IntoIterator<Item = impl Into<Cow<'static, str>>>, ) -> Self

Creates a foreign key with no ON DELETE / ON UPDATE actions.
