Enum TriggerTiming 

pub enum TriggerTiming {
    Before,
    After,
    InsteadOf,
}

Variants

Before

Fires before the row is written; the trigger function’s return value (NEW or NULL) decides the row content and whether the write proceeds at all.

After

Fires after the row is written; the return value is ignored.

InsteadOf

INSTEAD OF is PG-VIEW-trigger-only and out of scope for v7.12.4 (SPG has no updatable-view surface).

impl Eq for TriggerTiming

impl PartialEq for TriggerTiming

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