Enum TriggerOrder 

pub enum TriggerOrder {
    Follows {
        anchor: Ident,
        meta: Meta,
    },
    Precedes {
        anchor: Ident,
        meta: Meta,
    },
}

The MySQL {FOLLOWS | PRECEDES} <other_trigger> ordering clause of a CreateStoredTrigger (trigger_follows_precedes_clause): where the new trigger fires relative to an existing one on the same table and event.

The anchor is an Ident (MySQL’s ident_or_text — a bare or quoted trigger name) so both source spellings round-trip from its span. The keyword direction is the enum variant.

Variants

Follows

FOLLOWS <other> — fire immediately after the named trigger.

Fields

anchor: Ident

The anchor trigger this one follows.

meta: Meta

Source location and node identity.

Precedes

PRECEDES <other> — fire immediately before the named trigger.

Fields

anchor: Ident

The anchor trigger this one precedes.

meta: Meta

Source location and node identity.
