Struct ChatHistory 

pub struct ChatHistory {
    lines: Vec<(String, HistoryEntryType)>,
    open_tool_calls: HashMap<String, ToolCallParams>,
}

Chat history data

Fields

lines: Vec<(String, HistoryEntryType)>

Full chat history (split into lines, but not broken by terminal width)

open_tool_calls: HashMap<String, ToolCallParams>

Not-yet-resolved tool calls (for Self::push_raw())

Implementations

impl ChatHistory

pub fn push_raw(&mut self, agent: &Agent, msg: &ChatMessage)

Push and format a raw ChatMessage into the history.

pub fn lines(&self) -> &[(String, HistoryEntryType)]

Return the chat history.

pub fn push( &mut self, string: &str, kind: HistoryEntryType, force_new_line: bool, )

Append the given string of type ct to the history.

If force_new_line is false and the last line is of the same type, append to it; if it is true, always create a new line.

pub fn push_lines( &mut self, string: &str, kind: HistoryEntryType, force_new_line: bool, )

Append the given multi-line string to the history.

Splits string at newlines and appends each line as its own entry, so that entries in Self::lines() never span multiple physical lines.

If force_new_line is false and the last line is of the same type, append to it; if it is true, always create a new line.

pub fn force_resolve_unresolved_tool_calls(&mut self, agent: &mut Agent)

Force-resolve all open tool calls.

Push an error for each tool call that is in the history that has not yet received a result. This is useful after loading history from an existing session state, which may be incomplete.
