Enum TriggerOutcome 

pub enum TriggerOutcome {
    Row(Row),
    Skip,
}

What the trigger function returned. Drives the row-write path the trigger fired from.

Variants

Row(Row)

RETURN NEW; (or RETURN OLD;) — write this row. For BEFORE triggers, the row may differ from the input (e.g. NEW.search_vector := … rewrote a cell). For AFTER triggers, the value is currently ignored — but we still surface it for symmetric callers / future v7.12.5 use.

Skip

RETURN NULL; or trigger fell off the end. For a BEFORE trigger, the row writer must skip the affected row. For an AFTER trigger, no-op.

Trait Implementations

impl Clone for TriggerOutcome

fn clone(&self) -> TriggerOutcome

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TriggerOutcome

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TriggerOutcome

fn eq(&self, other: &TriggerOutcome) -> 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.
