Struct ContextBuilderService 

pub struct ContextBuilderService {
    recall: Option<RecallService>,
}

Service for building context for AI assistants.

Fields

recall: Option<RecallService>

Recall service for searching memories.

Implementations

impl ContextBuilderService

pub const fn new() -> Self

Creates a new context builder service.

pub const fn with_recall(recall: RecallService) -> Self

Creates a context builder with a recall service.

pub fn build_context(&self, max_tokens: usize) -> Result<String>

Builds context for the current session.

Errors

Returns an error if context building fails.

pub fn build_query_context( &self, query: &str, max_tokens: usize, ) -> Result<String>

Builds context for a specific query.

Errors

Returns an error if context building fails.

const fn get_relevant_memories( &self, _namespace: Namespace, _limit: usize, ) -> Result<Option<Vec<Memory>>>

Gets relevant memories for a namespace.

Returns None if recall service is not configured, otherwise returns an empty vector (placeholder for full storage integration).

pub const fn estimate_tokens(text: &str) -> usize

Estimates the token count for a string.

pub fn get_statistics(&self) -> Result<MemoryStatistics>

Gets memory statistics for session context.

Uses RecallService::list_all_with_content to fetch memories with full content for topic extraction. This is intentionally more expensive than the lightweight RecallService::list_all used by MCP tools.

Errors

Returns an error if statistics gathering fails.

Trait Implementations

impl Default for ContextBuilderService

fn default() -> Self

Returns the “default value” for a type.
