type PredictRequest struct {

	unknownFields protoimpl.UnknownFields

	// Required. Full resource name of the format:
	// {name=projects/*/locations/global/catalogs/default_catalog/placements/*}
	// The id of the recommendation engine placement. This id is used to identify
	// the set of models that will be used to make the prediction.
	//
	// We currently support three placements with the following IDs by default:
	//
	// * `shopping_cart`: Predicts products frequently bought together with one or
	//   more  products in the same shopping session. Commonly displayed after
	//   `add-to-cart` events, on product detail pages, or on the shopping cart
	//   page.
	//
	// * `home_page`: Predicts the next product that a user will most likely
	//   engage with or purchase based on the shopping or viewing history of the
	//   specified `userId` or `visitorId`. For example - Recommendations for you.
	//
	// * `product_detail`: Predicts the next product that a user will most likely
	//   engage with or purchase. The prediction is based on the shopping or
	//   viewing history of the specified `userId` or `visitorId` and its
	//   relevance to a specified `CatalogItem`. Typically used on product detail
	//   pages. For example - More products like this.
	//
	// * `recently_viewed_default`: Returns up to 75 products recently viewed by
	//   the specified `userId` or `visitorId`, most recent ones first. Returns
	//   nothing if neither of them has viewed any products yet. For example -
	//   Recently viewed.
	//
	// The full list of available placements can be seen at
	// https://console.cloud.google.com/recommendation/catalogs/default_catalog/placements
	Placement string `protobuf:"bytes,1,opt,name=placement,proto3" json:"placement,omitempty"`
	// Required. Context about the user, what they are looking at and what action
	// they took to trigger the predict request. Note that this user event detail
	// won't be ingested to userEvent logs. Thus, a separate userEvent write
	// request is required for event logging.
	UserEvent *UserEvent `protobuf:"bytes,2,opt,name=user_event,json=userEvent,proto3" json:"user_event,omitempty"`
	// Maximum number of results to return per page. Set this property
	// to the number of prediction results needed. If zero, the service will
	// choose a reasonable default. The maximum allowed value is 100. Values
	// above 100 will be coerced to 100.
	PageSize int32 `protobuf:"varint,3,opt,name=page_size,json=pageSize,proto3" json:"page_size,omitempty"`
	// The previous PredictResponse.next_page_token.
	PageToken string `protobuf:"bytes,4,opt,name=page_token,json=pageToken,proto3" json:"page_token,omitempty"`
	// Filter for restricting prediction results with a length limit of 5,000
	// characters. Accepts values for tags and the `filterOutOfStockItems` flag.
	//
	//  * Tag expressions. Restricts predictions to products that match all of the
	//    specified tags. Boolean operators `OR` and `NOT` are supported if the
	//    expression is enclosed in parentheses, and must be separated from the
	//    tag values by a space. `-"tagA"` is also supported and is equivalent to
	//    `NOT "tagA"`. Tag values must be double quoted UTF-8 encoded strings
	//    with a size limit of 1,000 characters.
	//
	//  * filterOutOfStockItems. Restricts predictions to products that do not
	//  have a
	//    stockState value of OUT_OF_STOCK.
	//
	// Examples:
	//
	//  * tag=("Red" OR "Blue") tag="New-Arrival" tag=(NOT "promotional")
	//  * filterOutOfStockItems  tag=(-"promotional")
	//  * filterOutOfStockItems
	//
	// If your filter blocks all prediction results, nothing will be returned. If
	// you want generic (unfiltered) popular products to be returned instead, set
	// `strictFiltering` to false in `PredictRequest.params`.
	Filter string `protobuf:"bytes,5,opt,name=filter,proto3" json:"filter,omitempty"`
	// Use validate only mode for this prediction query. If set to true, a
	// dummy model will be used that returns arbitrary products.
	// Note that the validate only mode should only be used for testing the API,
	// or if the model is not ready.
	ValidateOnly bool `protobuf:"varint,6,opt,name=validate_only,json=validateOnly,proto3" json:"validate_only,omitempty"`
	// Additional domain specific parameters for the predictions.
	//
	// Allowed values:
	//
	// * `returnProduct`: Boolean. If set to true, the associated product
	//    object will be returned in the `results.metadata` field in the
	//    prediction response.
	// * `returnScore`: Boolean. If set to true, the prediction 'score'
	//    corresponding to each returned product will be set in the
	//    `results.metadata` field in the prediction response. The given
	//    'score' indicates the probability of an product being clicked/purchased
	//    given the user's context and history.
	// * `strictFiltering`: Boolean. True by default. If set to false, the service
	//    will return generic (unfiltered) popular products instead of empty if
	//    your filter blocks all prediction results.
	Params map[string]*structpb.Value `protobuf:"bytes,7,rep,name=params,proto3" json:"params,omitempty" protobuf_key:"bytes,1,opt,name=key,proto3" protobuf_val:"bytes,2,opt,name=value,proto3"`
	// The labels for the predict request.
	//
	//  * Label keys can contain lowercase letters, digits and hyphens, must start

	//  * Non-zero label values can contain lowercase letters, digits and hyphens,
	//    must start with a letter, and must end with a letter or digit.
