Struct Messages 

pub struct Messages(pub Vec<Message>);

A conversation: an ordered list of turns.

Carried between nodes as a Value::Json under this exact shape, so any consumer — Rust, Python, the report renderer — reads the same structure.

Tuple Fields

0: Vec<Message>

Implementations

impl Messages

pub fn new() -> Self

An empty conversation.

pub fn push(&mut self, message: Message)

Append a turn.

pub fn len(&self) -> usize

How many turns so far.

pub fn is_empty(&self) -> bool

Whether no turn has been added yet.

pub fn iter(&self) -> Iter<'_, Message>

Iterate over the turns, oldest first.

pub fn last(&self) -> Option<&Message>

The most recent turn, if any.

pub fn to_value(&self) -> Value

Encode as the Value that travels along an edge.

pub fn from_value(value: &Value) -> Result<Self>

Read a conversation off an edge.

Accepts three shapes, in decreasing specificity: a full message list, a bare string (promoted to a single user turn), and a Value::Text (likewise). The promotions exist so a plain prompt can feed a node expecting a conversation without ceremony — the common first hop.

Trait Implementations

impl Clone for Messages

fn clone(&self) -> Messages

Returns a duplicate of the value.

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

Performs copy-assignment from source.
