Enum Kpi 

pub enum Kpi {
    Tokens,
    CacheTokens,
    Cost,
    Prompts,
    ToolCalls,
    StopReason,
    DurationMs,
    Sidechain,
}

A measurable a report might want to show. An adapter that does not list a KPI cannot fill it in from its logs — the column is blank because the data does not exist, not because the number is zero.

Variants

Tokens

input_tok / output_tok.

CacheTokens

cache_read_tok / cache_write_tok.

Cost

cost_est, derived from configured pricing.

Prompts

Prompt text and text_hash.

ToolCalls

tool_calls.

StopReason

stop_reason.

DurationMs

Per-turn wall-clock time.

Sidechain

Whether an event came from a subagent transcript.

Implementations

impl Kpi

pub const ALL: [Kpi; 8]

Every KPI warden knows about, in display order.

pub fn label(self) -> &'static str

Short label used by doctor and report headers.

Trait Implementations

impl Eq for Kpi

impl Ord for Kpi

fn cmp(&self, other: &Kpi) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Kpi

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Kpi

fn partial_cmp(&self, other: &Kpi) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
