Struct MessageGroup 

pub struct MessageGroup {
    pub group_type: MessageGroupType,
    pub primary: Message,
    pub tool_calls: Vec<ToolCallWithResult>,
    pub start_timestamp: Option<String>,
    pub end_timestamp: Option<String>,
}

A group of related messages for consolidated rendering.

Represents a logical unit of conversation: a primary message (user question or assistant response) along with all associated tool calls and their results. This enables rendering an entire interaction as a cohesive block rather than separate messages.

Fields

group_type: MessageGroupType

Group type for rendering decisions.

primary: Message

The primary message (user or assistant text).

tool_calls: Vec<ToolCallWithResult>

Tool calls paired with their results.

start_timestamp: Option<String>

Timestamp of the first message/action in this group.

end_timestamp: Option<String>

Timestamp of the last message/action in this group.

Implementations

impl MessageGroup

pub fn new(primary: Message, group_type: MessageGroupType) -> Self

Create a new message group with a primary message.

pub fn user(primary: Message) -> Self

Create a user message group.

pub fn assistant(primary: Message) -> Self

Create an assistant message group.

pub fn system(primary: Message) -> Self

Create a system message group.

pub fn tool_only(primary: Message) -> Self

Create a tool-only group (orphan tool calls).

pub fn add_tool_call(&mut self, call: ToolCall, correlation_id: Option<String>)

Add a tool call to this group.

pub fn add_tool_result(&mut self, result: ToolResult)

Add a tool result, matching it with an existing call by correlation ID.

If a matching call is found, the result is attached to it. If no match is found, the result is dropped with a warning.

pub fn update_end_timestamp(&mut self, timestamp: Option<String>)

Update the end timestamp if the given timestamp is later.

pub fn tool_count(&self) -> usize

Get the number of tool calls in this group.

pub fn has_errors(&self) -> bool

Check if any tool call in this group resulted in an error.

pub fn all_tools_complete(&self) -> bool

Check if all tool calls have results.

pub fn tool_summary(&self) -> (usize, usize, usize)

Get a summary of tool call statuses for display.

Trait Implementations

impl Clone for MessageGroup

fn clone(&self) -> MessageGroup

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessageGroup

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
