Struct PolicyMemory 

pub struct PolicyMemory<M, P> { /* private fields */ }

Wrap a ConversationMemory backend with a MemoryPolicy, propagating policy errors to the caller as MemoryError::Policy.

This is the hard-fail counterpart to InMemoryConversationMemory::with_filter + IntoFilter::into_filter. with_filter swallows policy errors and returns the unfiltered history; PolicyMemory surfaces them so callers can decide how to react.

Example

use rig_memory::{InMemoryConversationMemory, PolicyMemory, SlidingWindowMemory};

let memory = PolicyMemory::new(
    InMemoryConversationMemory::new(),
    SlidingWindowMemory::last_messages(20),
);

Implementations

impl<M, P> PolicyMemory<M, P>

pub fn new(inner: M, policy: P) -> Self

Wrap inner so every loaded history is run through policy.

pub fn inner(&self) -> &M

Return a reference to the wrapped backend.

pub fn policy(&self) -> &P

Return a reference to the wrapped policy.

pub fn into_inner(self) -> (M, P)

Consume the wrapper and return the underlying backend and policy.
