Struct google_cognitive_apis::api::grpc::google::cloud::dialogflow::cx::v3::EventHandler

pub struct EventHandler {
    pub name: String,
    pub event: String,
    pub trigger_fulfillment: Option<Fulfillment>,
    pub target: Option<Target>,
}

An event handler specifies an [event][google.cloud.dialogflow.cx.v3.EventHandler.event] that can be handled during a session. When the specified event happens, the following actions are taken in order:

• If there is a [trigger_fulfillment][google.cloud.dialogflow.cx.v3.EventHandler.trigger_fulfillment] associated with the event, it will be called.
• If there is a [target_page][google.cloud.dialogflow.cx.v3.EventHandler.target_page] associated with the event, the session will transition into the specified page.
• If there is a [target_flow][google.cloud.dialogflow.cx.v3.EventHandler.target_flow] associated with the event, the session will transition into the specified flow.

Fields

name: String

Output only. The unique identifier of this event handler.

event: String

Required. The name of the event to handle.

trigger_fulfillment: Option<Fulfillment>

The fulfillment to call when the event occurs. Handling webhook errors with a fulfillment enabled with webhook could cause infinite loop. It is invalid to specify such fulfillment for a handler handling webhooks.

target: Option<Target>

The target to transition to, either a page in the same host flow (the flow that owns this [TransitionRoute][google.cloud.dialogflow.cx.v3.TransitionRoute]), or another flow in the same agent.

Trait Implementations

impl Clone for EventHandler

fn clone(&self) -> EventHandler

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EventHandler

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

Formats the value using the given formatter.

impl Default for EventHandler

fn default() -> Self

Returns the “default value” for a type.

impl Message for EventHandler

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8, Global>

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8, Global>

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    B: Buf,
    Self: Default, 

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    B: Buf,
    Self: Default, 

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq<EventHandler> for EventHandler

fn eq(&self, other: &EventHandler) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
