}Expand description
Core memory storage trait.
Implementations must be Send + Sync for sharing across async tasks.
The trait abstracts over storage backends (SQLite, in-memory, remote)
while ensuring consistent behavior for compaction and retrieval.
Required Methods§
Sourcefn ingest<'life0, 'life1, 'life2, 'async_trait>(
&'life0 self,
role: &'life1 str,
content: &'life2 str,
token_count: usize,
) -> Pin<Box<dyn Future<Output = Result<i64>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
'life2: 'async_trait,
fn ingest<'life0, 'life1, 'life2, 'async_trait>(
&'life0 self,
role: &'life1 str,
content: &'life2 str,
token_count: usize,
) -> Pin<Box<dyn Future<Output = Result<i64>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
'life2: 'async_trait,
Ingest a new message into the store.
Called synchronously on the message processing path. Implementations should avoid blocking I/O where possible.
Sourcefn search<'life0, 'life1, 'async_trait>(
&'life0 self,
query: &'life1 str,
limit: usize,
) -> Pin<Box<dyn Future<Output = Result<Vec<MemoryHit>>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
fn search<'life0, 'life1, 'async_trait>(
&'life0 self,
query: &'life1 str,
limit: usize,
) -> Pin<Box<dyn Future<Output = Result<Vec<MemoryHit>>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
Full-text search across all stored messages and summaries.
Returns up to limit results ordered by relevance score.
Sourcefn get_context<'life0, 'async_trait>(
&'life0 self,
max_tokens: usize,
) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'async_trait>>where
Self: 'async_trait,

fn get_context<'life0, 'async_trait>(
&'life0 self,
max_tokens: usize,
) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
Generate context string for agent bootstrap.
Returns a formatted string of recent messages and summaries,
respecting max_tokens budget. Used for system prompt injection.
Sourcefn get_context_entries<'life0, 'async_trait>(
&'life0 self,
max_tokens: usize,
) -> Pin<Box<dyn Future<Output = Result<Vec<MemoryEntry>>> + Send + 'async_trait>>where
Self: 'async_trait,

&'life0 self,
max_tokens: usize,
) -> Pin<Box<dyn Future<Output = Result<Vec<MemoryEntry>>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
Get recent context entries for the agent.
Returns the most recent entries up to max_tokens budget.
Sourcefn compact<'life0, 'life1, 'async_trait>(
&'life0 self,
summarizer: &'life1 dyn Summarizer,
) -> Pin<Box<dyn Future<Output = Result<CompactionStats>> + Send + 'async_trait>>where

'life0: 'async_trait,
'life1: 'async_trait,
fn compact<'life0, 'life1, 'async_trait>(

Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
Run compaction if thresholds are exceeded.
Compresses older messages into summaries using the configured summarization backend. Safe to call frequently; returns early if no compaction needed.
