Implementations

impl ForeignKey

pub fn new<C, R>( columns: impl IntoIterator<Item = C>, ref_table: impl IntoIden, ref_columns: impl IntoIterator<Item = R>, ) -> ForeignKey

where C: IntoIden, R: IntoIden,

Builds FOREIGN KEY (columns) REFERENCES table (ref_columns).

pub fn name(self, name: impl IntoIden) -> ForeignKey

Sets the constraint name.

pub fn on_delete(self, action: ForeignKeyAction) -> ForeignKey

Sets ON DELETE action.

pub fn on_update(self, action: ForeignKeyAction) -> ForeignKey

Sets ON UPDATE action.
