Implementations

impl Message

pub fn system(content: &str) -> Self

Constructs a system message.

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Message

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Message> for Message

Conversion from provider Message to a completion message. This is needed so that responses can be converted back into chat history.

An assistant message with empty content and no thinking or tool calls converts to empty message content — no fabricated empty-text block. Such a message cannot be replayed through the request boundary (validate_message_content rejects a content-less assistant message); callers ingesting raw Ollama history should filter empty assistant messages rather than expect rig to invent content for them. The agent loop never produces this shape: it drops empty turns before history.

fn from(msg: Message) -> Self

Converts to this type from the input type.

impl PartialEq for Message

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Message

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
