Enum Flag 

pub enum Flag {
    LowPower,
    CiCrossesZero,
    NoPricing,
}

Caveat flags attached to a per-axis result.

Flags explain why the severity is what it is — they surface the statistical caveats that users would otherwise have to read the CI and n column to spot. A severity of Severe with no flags is strong; a severity of Severe with LowPower means “the trend looks large but our sample was too small to be confident.”

Variants

LowPower

n < 5 — we don’t have enough paired observations to be confident in the CI. Bootstrap on tiny samples produces wide intervals; treat severities as directional, not definitive.

CiCrossesZero

The 95% CI includes zero. At the 95% confidence level we cannot reject “no effect”; the observed delta may be noise. Severity is capped at Minor in this case regardless of |delta|.

NoPricing

Cost axis could not price any pair — either no pricing table was supplied or the table has no entries for the traced models. A 0.00 cost delta in this state means “unknown”, not “equal”. Emitted only on Axis::Cost.

Implementations

impl Flag

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

Short machine-readable label for terminal / markdown / JSON output.

Trait Implementations

impl Clone for Flag

fn clone(&self) -> Flag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Flag

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Flag

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Flag

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Flag

fn cmp(&self, other: &Flag) -> 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 Flag

fn eq(&self, other: &Flag) -> 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.

impl PartialOrd for Flag

fn partial_cmp(&self, other: &Flag) -> 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.

impl Serialize for Flag

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Flag

impl Eq for Flag
