Struct InMemoryMemory 

pub struct InMemoryMemory { /* private fields */ }

In-memory implementation: stores all messages verbatim.

The simplest Memory implementation: all messages are kept in memory with no trimming, no summarization, and no persistence; context() returns a full clone. Default constructs an empty session.

Comparison

Compared to WindowMemory: the latter trims to a recent window on retrieval, suiting long conversations (the model’s context window is finite); this implementation has no budget control — messages only grow — suiting small conversations that need the full history.

Example

use molo::memory::{InMemoryMemory, Memory};

let mut memory = InMemoryMemory::default();
memory.record(molo::Message::system("setup")).await?;
memory.record(molo::Message::user("hello")).await?;
memory.record(molo::Message::assistant("hello!")).await?;

let context = memory.context().await?;
assert_eq!(context.len(), 3);
assert_eq!(context[0], molo::Message::System("setup".into()));

Trait Implementations

impl Debug for InMemoryMemory

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

Formats the value using the given formatter.

impl Default for InMemoryMemory

fn default() -> InMemoryMemory

Returns the “default value” for a type.

impl Memory for InMemoryMemory

fn record<'life0, 'async_trait>( &'life0 mut self, message: Message, ) -> Pin<Box<dyn Future<Output = Result<(), MemoryError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Records a message, appending it to the end of the session context.

fn context<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<Message>, MemoryError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Returns the full message sequence of the current context (in order of occurrence), which the agent hands to the Provider as-is.

fn record_protected<'life0, 'async_trait>( &'life0 mut self, message: Message, ) -> Pin<Box<dyn Future<Output = Result<(), MemoryError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Records a protected message: implementations must not remove it when trimming.
