pub fn before(self) -> Self

Set timing to BEFORE.

pub fn after(self) -> Self

Set timing to AFTER.

pub fn instead_of(self) -> Self

Set timing to INSTEAD OF.

pub fn on(self, events: Vec<TriggerEvent>) -> Self

Set events.

pub fn for_each_row(self) -> Self

Set as row-level trigger.

pub fn for_each_statement(self) -> Self

Set as statement-level trigger.

pub fn when(self, condition: impl Into<String>) -> Self

Set WHEN condition.

pub fn execute(self, function: impl Into<String>) -> Self

Trait Implementations

impl Clone for TriggerDefinition

fn clone(&self) -> TriggerDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TriggerDefinition

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

Formats the value using the given formatter.

impl Default for TriggerDefinition

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TriggerDefinition

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TriggerDefinition

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

impl Serialize for TriggerDefinition

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
