Struct Message 

#[non_exhaustive]
pub struct Message {
    pub role: Role,
    pub parts: Vec<Part>,
}

One turn of a conversation: a role, and its parts in order.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

role: Role

Who it is from.

parts: Vec<Part>

What it says, in order.

Implementations

impl Message

pub fn new(role: Role) -> Self

An empty message from role.

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

A user message with this text. Empty text adds no part, so Message::user("") followed by images carries only the images.

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

A model message with this text, for example when replaying a stored conversation.

pub fn tool_result(result: ToolResult) -> Self

A message carrying the result of one tool call.

pub fn with(self, part: impl Into<Part>) -> Self

Adds a part after the ones already there.
