pub struct ConversationHistory {
    pub turns: Vec<ConversationTurn>,
    pub compacted: Vec<CompactedTurn>,
    pub max_turns: usize,
}

Conversation history.

Fields

turns: Vec<ConversationTurn>

Conversation turns.

compacted: Vec<CompactedTurn>

Compacted (summarized) history.

max_turns: usize

Maximum turns to keep before compacting.

Implementations

impl ConversationHistory

pub fn new() -> Self

Creates a new empty history.

pub fn len(&self) -> usize

Returns the number of turns.

pub fn is_empty(&self) -> bool

Returns true if empty.

pub fn recent(&self, n: usize) -> &[ConversationTurn]

Returns the most recent N turns.

pub fn search(&self, keyword: &str) -> Vec<&ConversationTurn>

Searches turns by keyword.

pub fn in_range(&self, start_ms: u64, end_ms: u64) -> Vec<&ConversationTurn>

Filters turns by time range.

pub fn compact(&mut self, summarizer: impl Fn(&[ConversationTurn]) -> String)

Compacts old turns using the provided summarizer.

If the number of turns exceeds max_turns, older turns are summarized and moved to compacted.
