Struct SlidingWindowMemory 

pub struct SlidingWindowMemory { /* private fields */ }

A MemoryPolicy that retains only the most recent max_messages entries.

When the window starts mid-conversation, a leading orphan tool-result message (a Message::User whose first content is a tool result without its preceding Message::Assistant tool call) is dropped to preserve the tool-call/result pairing required by most providers.

Implementations

impl SlidingWindowMemory

pub fn last_messages(n: usize) -> Self

Keep at most n messages.

Trait Implementations

impl Clone for SlidingWindowMemory

fn clone(&self) -> SlidingWindowMemory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SlidingWindowMemory

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

Formats the value using the given formatter.

impl MemoryPolicy for SlidingWindowMemory

fn apply(&self, messages: Vec<Message>) -> Result<Vec<Message>, MemoryError>

Transform messages into the history that should be returned to the agent. This is the required method — every policy must implement it.

fn apply_with_demoted( &self, messages: Vec<Message>, ) -> Result<(Vec<Message>, Vec<Message>), MemoryError>

Transform messages and report which messages were demoted (excluded from the returned history).
