pub struct LlmResponse {
    pub content: Option<Content>,
    pub usage_metadata: Option<UsageMetadata>,
    pub finish_reason: Option<FinishReason>,
    pub citation_metadata: Option<CitationMetadata>,

Core traits and types.

Always available regardless of feature flags. Includes:

• Agent - The fundamental trait for all agents
• Tool / Toolset - For extending agents with capabilities
• Session / State - For managing conversation context
• Event - For streaming agent responses
• AdkError / Result - Unified error handling A response from an LLM provider.

Fields

content: Option<Content>

The generated content (text, function calls, etc.).

usage_metadata: Option<UsageMetadata>

Token usage statistics.

finish_reason: Option<FinishReason>

Reason the model stopped generating.

citation_metadata: Option<CitationMetadata>

Citation sources referenced in the response.

partial: bool

Whether this is a partial streaming chunk.

turn_complete: bool

Whether the model has finished its turn.

interrupted: bool

Whether the response was interrupted.

error_code: Option<String>

Error code from the provider, if any.

error_message: Option<String>

Error message from the provider, if any.

provider_metadata: Option<Value>

Provider-specific metadata (e.g., response IDs, routing info).

interaction_id: Option<String>

Interactions API: the server-assigned interaction id for this turn, used to continue the conversation via previous_interaction_id. None for the generateContent transport and non-Gemini providers.
