public sealed class GenerateGroundedContentRequest : IMessage<GenerateGroundedContentRequest>, IEquatable<GenerateGroundedContentRequest>, IDeepCloneable<GenerateGroundedContentRequest>, IBufferMessage, IMessage
Reference documentation and code samples for the Discovery Engine v1 API class GenerateGroundedContentRequest.
Top-level message sent by the client for the GenerateGroundedContent
method.
public RepeatedField<GroundedGenerationContent> Contents { get; }
Content of the current conversation with the model.
For single-turn queries, this is a single instance. For multi-turn queries,
this is a repeated field that contains conversation history + latest
request.
public MapField<string, string> UserLabels { get; }
The user labels applied to a resource must meet the following requirements:
Each resource can have multiple labels, up to a maximum of 64.
Each label must be a key-value pair.
Keys have a minimum length of 1 character and a maximum length of 63
characters and cannot be empty. Values can be empty and have a maximum
length of 63 characters.
Keys and values can contain only lowercase letters, numeric characters,
underscores, and dashes. All characters must use UTF-8 encoding, and
international characters are allowed.
The key portion of a label must be unique. However, you can use the same
key with multiple resources.
Keys must start with a lowercase letter or international character.
