Struct Transcript 

pub struct Transcript {
    pub reasoning: String,
    pub text: String,
    pub tool_calls: Vec<(String, String)>,
    pub finish_reason: Option<String>,
    pub completion_tokens: usize,
    pub cached_prompt_tokens: usize,
}

2026-09-26: The comparable part of one reply.

Fields

reasoning: String

2026-09-26: Kept apart from text, as ChatOutcome does, so a change of reasoning is not hidden by an identical answer.

text: String

tool_calls: Vec<(String, String)>

2026-09-26: (name, raw arguments). Arguments stay raw: re-serialising the JSON would normalise key order and whitespace.

finish_reason: Option<String>

completion_tokens: usize

2026-09-26: ChatOutcome::completion_tokens: the server’s usage.completion_tokens when the stream carries it, else the streamed delta count.

cached_prompt_tokens: usize

2026-09-26: Diagnostic: not in canonical, so no divergence check here compares it. The SSM poisoning gate reads it as its turn-1 cache count.

Implementations

impl Transcript

pub fn canonical(&self) -> String

2026-09-26: The text a divergence check compares, concatenated in a fixed order with control-character separators; callers also use it for longest-common-prefix localisation. The token counts are left out: callers compare completion_tokens separately.

pub fn carries_foreign_canary<'a>( &self, own: &str, all: &[&'a str], ) -> Option<&'a str>

2026-09-26: The first canary in all, other than own, that appears in this reply’s canonical text. Unlike a diff, it needs no reference.

Trait Implementations

impl Clone for Transcript

fn clone(&self) -> Transcript

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transcript

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

Formats the value using the given formatter.

impl Default for Transcript

fn default() -> Transcript

Returns the “default value” for a type.

impl From<&ChatOutcome> for Transcript

fn from(o: &ChatOutcome) -> Self

Converts to this type from the input type.

impl PartialEq for Transcript

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
