Implementations

impl Message

pub fn new( model: impl Into<String>, role: MessageRole, content: Vec<ContentBlock>, ) -> Self

Create a new message

pub fn get_text_content(&self) -> String

Get all text content from the message

pub fn get_tool_uses(&self) -> Vec<(&str, &str, &Value)>

Get all tool uses from the message

pub fn used_tools(&self) -> bool

Check if message ended due to tool use

pub fn is_complete(&self) -> bool

Check if message is complete

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 PartialEq for Message

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

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.
