Implementations

impl ConversationMemory

pub fn new(config: MemoryConfig) -> Self

Create a new memory with the given config.

pub fn with_defaults() -> Self

Create a new memory with default configuration (5 turns, 4000 chars).

pub fn record_turn(&mut self, role: Role, content: impl Into<String>)

Record a new conversation turn, evicting the oldest if over max_turns.

pub fn format_context(&self) -> String

Format the stored turns as a context string for injection.

Builds the context from most recent turns backward, stopping when adding the next turn would exceed budget_chars. Returns the context in chronological order.

pub fn clear(&mut self)

Remove all recorded turns.

pub fn is_empty(&self) -> bool

Whether there are no recorded turns.

pub fn config(&self) -> &MemoryConfig

Current configuration.
