Struct Message 

pub struct Message {
    pub role: MessageRole,
    pub content: MessageContent,
    pub tool_call_id: Option<String>,
}

Unified message structure

Fields

role: MessageRole

content: MessageContent

tool_call_id: Option<String>

Required when role is Tool (OpenAI API: tool_call_id).

Implementations

impl Message

pub fn system(text: impl Into<String>) -> Message

pub fn user(text: impl Into<String>) -> Message

pub fn assistant(text: impl Into<String>) -> Message

pub fn tool( tool_call_id: impl Into<String>, content: impl Into<String>, ) -> Message

Create a tool result message for multi-turn tool calling.

OpenAI and similar APIs expect role: "tool" with tool_call_id and content.

pub fn with_content(role: MessageRole, content: MessageContent) -> Message

pub fn contains_image(&self) -> bool

pub fn contains_audio(&self) -> bool
