Implementations

impl Message

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

A user message carrying a single run of text.

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

An assistant message carrying a single run of text.

pub fn user_blocks(blocks: Vec<ContentBlock>) -> Message

A user message built from explicit content blocks.

pub fn assistant_blocks(blocks: Vec<ContentBlock>) -> Message

An assistant message built from explicit content blocks.

pub fn tool_result( tool_use_id: impl Into<String>, content: impl Into<String>, ) -> Message

The user message that answers a tool call, ready to append to the conversation as the follow-up turn.

tool_use_id must match the id of the ContentBlock::ToolUse block from the assistant’s previous turn. This is the ergonomic path for the common case where a tool returns a string result.
