Struct ChatState 

pub struct ChatState {
    pub messages: Vec<Message>,
}

State for crate::create_chat_agent and the simplest single-turn recipes — just the conversation so far.

Fields

messages: Vec<Message>

The conversation, oldest first. The agent appends one assistant message per invocation.

Implementations

impl ChatState

pub fn from_user(text: impl Into<String>) -> Self

Build a state with a single user message.

pub fn last_assistant_text(&self) -> Option<String>

Concatenated user-facing text of the most recent assistant message. None when no assistant message exists or only non-text content was emitted (tool calls only).

Trait Implementations

impl Clone for ChatState

fn clone(&self) -> ChatState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChatState

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

Formats the value using the given formatter.

impl Default for ChatState

fn default() -> ChatState

Returns the “default value” for a type.

impl PartialEq for ChatState

fn eq(&self, other: &ChatState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
