LlmEventSummarizer

adk_rust::agent

Struct LlmEventSummarizer 

Source 
pub struct LlmEventSummarizer { /* private fields */ }
Available on crate feature agents only.
Expand description

An LLM-based event summarizer for sliding window compaction.

When called with a list of events, this formats the events, generates a summary using an LLM, and returns a new Event containing the summary within an EventCompaction.

Implementations§

Source§

impl LlmEventSummarizer

Source

pub fn new(llm: Arc<dyn Llm>) -> LlmEventSummarizer

Create a new summarizer using the given LLM.

Source

pub fn with_prompt_template( self, template: impl Into<String>, ) -> LlmEventSummarizer

Create a new summarizer with a custom prompt template. The template must contain {conversation_history} as a placeholder.

Trait Implementations§

impl BaseEventsSummarizer for LlmEventSummarizer

Source§

fn summarize_events<'life0, 'life1, 'async_trait>( &'life0 self, events: &'life1 [Event], ) -> Pin<Box<dyn Future<Output = Result<Option<Event>, AdkError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, LlmEventSummarizer: 'async_trait,
