Struct google_api_proto::google::actions::sdk::v2::interactionmodel::ConditionalEvent

pub struct ConditionalEvent {
    pub condition: String,
    pub transition_to_scene: String,
    pub handler: Option<EventHandler>,
}

Registers events that trigger as the result of a true condition.

Fields

condition: String

Required. Filter condition for this event to trigger. If condition is evaluated to true then the associated handler will be triggered. The following variable references are supported: $session - To reference data in session storage. $user - To reference data in user storage. The following boolean operators are supported (with examples): && - session.params.counter > 0 && session.params.counter < 100 || - session.params.foo == "John" || session.params.counter == "Adam" ! - !(session.params.counter == 5) The following comparisons are supported: ==, !=, <, >, <=, >= The following list and string operators are supported (with examples): in - “Watermelon” in session.params.fruitList size - size(session.params.fruitList) > 2 substring - session.params.fullName.contains("John")

transition_to_scene: String

Optional. Destination scene which the conversation should jump to when the associated condition is evaluated to true. The state of the current scene is destroyed on the transition.

handler: Option<EventHandler>

Optional. Event handler which is triggered when the associated condition is evaluated to true. Should execute before transitioning to the destination scene. Useful to generate Prompts in response to events.

Trait Implementations

impl Clone for ConditionalEvent

fn clone(&self) -> ConditionalEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConditionalEvent

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

Formats the value using the given formatter.

impl Default for ConditionalEvent

fn default() -> Self

Returns the “default value” for a type.

impl Message for ConditionalEvent

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

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

where Self: Sized,

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

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

where Self: Sized,

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

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

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

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

where Self: Sized,

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

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

where Self: Sized,

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

impl PartialEq for ConditionalEvent

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