Struct InMemoryConversationMemory 

pub struct InMemoryConversationMemory { /* private fields */ }

A simple thread-safe in-memory ConversationMemory backed by a HashMap.

Messages are stored in process memory only and lost on restart. Useful for tests, examples, and short-lived agents. Pass a closure to InMemoryConversationMemory::with_filter to apply a history-shaping transformation on every load (truncation, summarization, re-ordering, etc.). Reusable named policies live in the rig-memory companion crate.

Implementations

impl InMemoryConversationMemory

pub fn new() -> Self

Create an empty in-memory store with no filter.

pub fn with_filter<F>(self, filter: F) -> Self

where F: MessageFilter + 'static,

Replaces the filter applied to each loaded history after releasing the store lock. Filtering does not modify stored messages.

Trait Implementations

impl Clone for InMemoryConversationMemory

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ConversationMemory for InMemoryConversationMemory

fn load<'a>( &'a self, conversation_id: &'a ConversationId, ) -> WasmBoxedFuture<'a, Result<Vec<Message>, MemoryError>>

Load the full conversation history for conversation_id.

fn append<'a>( &'a self, conversation_id: &'a ConversationId, messages: Vec<Message>, ) -> WasmBoxedFuture<'a, Result<(), MemoryError>>

Append messages to the conversation identified by conversation_id.

fn clear<'a>( &'a self, conversation_id: &'a ConversationId, ) -> WasmBoxedFuture<'a, Result<(), MemoryError>>

Remove all stored messages for conversation_id.

impl Debug for InMemoryConversationMemory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InMemoryConversationMemory

fn default() -> Self

Returns the “default value” for a type.
