Enum TriggerEvent 

pub enum TriggerEvent {
    Delete {
        meta: Meta,
    },
    Insert {
        meta: Meta,
    },
    Update {
        columns: ThinVec<Ident>,
        meta: Meta,
    },
}

The DML event that fires a CreateTrigger.

UPDATE alone fires on any column; UPDATE OF a, b restricts it to the listed columns (columns empty for the bare UPDATE). INSERT and DELETE take no column list.

Variants

Delete

DELETE — fire on row deletion.

Fields

meta: Meta

Source location and node identity.

Insert

INSERT — fire on row insertion.

Fields

meta: Meta

Source location and node identity.

Update

UPDATE [OF col, …] — fire on row update, optionally restricted to columns.

Fields

columns: ThinVec<Ident>

Columns in source order.

meta: Meta

Source location and node identity.
