    pub content: String,
    pub name: Option<String>,
    pub tool_call_id: Option<String>,
}

Fields

role: Role

name: Option<String>

tool_call_id: Option<String>

Tool call ID (for tool role messages)

Implementations

impl Message

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

Create a user message.

Example

use simple_agent_type::message::{Message, Role};

let msg = Message::user("Hello!");
assert_eq!(msg.role, Role::User);
assert_eq!(msg.content, "Hello!");

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

Create an assistant message.

Example

use simple_agent_type::message::{Message, Role};

let msg = Message::assistant("Hi there!");
assert_eq!(msg.role, Role::Assistant);

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

Create a system message.

Example

use simple_agent_type::message::{Message, Role};

let msg = Message::system("You are a helpful assistant.");
assert_eq!(msg.role, Role::System);

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

Create a tool message.

Example

use simple_agent_type::message::{Message, Role};

let msg = Message::tool("result", "call_123");
assert_eq!(msg.role, Role::Tool);
assert_eq!(msg.tool_call_id, Some("call_123".to_string()));

pub fn with_name(self, name: impl Into<String>) -> Message

Set the name field (builder pattern).

Example

use simple_agent_type::message::Message;

let msg = Message::user("Hello").with_name("Alice");
assert_eq!(msg.name, Some("Alice".to_string()));

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<(), Error>

Formats the value using the given formatter.

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<Message, <__D as Deserializer<'de>>::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 as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
