Struct ParsedLine 

pub struct ParsedLine {
    pub text: Option<String>,
    pub thinking: Option<String>,
    pub session: Option<SessionInfo>,
    pub tool_start: Option<ToolCallStart>,
    pub tool_end: Option<ToolCallEnd>,

}

What a single harness output line decoded to. A line can yield text and edits at once, so this is not one-event-per-line.

Fields

text: Option<String>

thinking: Option<String>

Model reasoning chunk → RunEvent::Thinking. Kept separate from text so the UI can render it distinctly.

session: Option<SessionInfo>

Session identity (id + model) → RunEvent::Session.

tool_start: Option<ToolCallStart>

A tool call began → RunEvent::ToolStart.

tool_end: Option<ToolCallEnd>

A tool call finished → RunEvent::ToolEnd.

edits: Vec<SuggestedEdit>

usage: Option<UsageInfo>

Token accounting → RunEvent::Usage.

activity: Option<String>

error: Option<String>

An in-band failure the harness reported on its stdout (codex’s turn.failed / error lines) → RunEvent::Error. Terminal. Kept distinct from activity so a real failure (quota mid-turn, context overflow, model error) surfaces as an error instead of being downgraded to transient narration — otherwise a failed turn yields no answer and no error, looking like the harness silently did nothing.

ask_question: Option<(String, Vec<Question>)>

A harness asked the user a multiple-choice question (Claude’s AskUserQuestion) → RunEvent::AskQuestion. The tuple is (request_id, questions): the tool-call id the host echoes when tying the answer and clearing the chips, plus the parsed questions. The host renders the options as chips; the answer returns as the user’s next message.

plan: Option<Vec<PlanEntry>>

The agent’s current plan / todo list → RunEvent::Plan. No built-in parser fills this yet; it’s wired for adapters that will.

title: Option<String>

A live session-title update → RunEvent::SessionInfoUpdate.

Implementations

impl ParsedLine

pub fn is_empty(&self) -> bool

True when a line decoded to no actionable content. A useful predicate for adapters + their tests; the normalize skeleton relies instead on the natural no-op of pushing zero events.

Trait Implementations

impl Clone for ParsedLine

fn clone(&self) -> ParsedLine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParsedLine

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

Formats the value using the given formatter.

impl Default for ParsedLine

fn default() -> ParsedLine

Returns the “default value” for a type.

impl Eq for ParsedLine

impl PartialEq for ParsedLine

fn eq(&self, other: &ParsedLine) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
