Struct TurnTrace 

struct TurnTrace {
    opened: Option<String>,
    ended: Option<String>,
    stopped: Option<StopReason>,
    worked: bool,
}

The facts a turn’s own rows carry, gathered while the fold walks them.

A transcript holds no result frame, so a turn read from one has no name of its own unless one is derived here: the CLI writes that frame to the wire and not to the file.

Fields

opened: Option<String>

The first and last clocks the turn’s rows carried.

ended: Option<String>

stopped: Option<StopReason>

The stop the turn’s last assistant frame reported. A frame handing back for a tool call has not ended a turn.

worked: bool

Whether the turn wrote an assistant frame at all: a prompt nothing answered draws no row, the way a view draws none.

Implementations

impl TurnTrace

fn watch(&mut self, message: &Message)

fn clock(&mut self, at: Option<&str>)

fn span_ms(&self) -> Option<u64>

The span the turn’s own rows support: None when either end does not parse or the pair runs backwards, which a transcript does hand back - a replayed row carries the stamp it was written with, so it can sit behind the row before it. The header prints a span and nothing else where one belongs, so a turn with no usable span draws no row: a zero there would be a measurement this row does not have.

fn drew_work(&self) -> bool

Whether the turn ran anything worth a row at all.

fn stopped_of_its_own_accord(&self) -> bool

Whether the turn’s own last frame ended it rather than handing back for a tool call. Only a turn closing at the end of a conversation needs this: a turn the next prompt closed is over whatever its last frame stopped for.

Trait Implementations

impl Default for TurnTrace

fn default() -> Self

Returns the “default value” for a type.
