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,

Apply filter to the loaded message list on every load.

The filter runs after raw messages are read from the store and before they are returned to the agent. Use it for truncation, summarization, or any other shaping. For reusable named policies, depend on rig-memory.

Trait Implementations
