Enum Direction 

pub enum Direction {
    Neutral,
    LowerBetter,
    HigherBetter,
}

Whether a metric’s delta is “good” when it moves up or down — drives the green/red colouring in the viewer. Neutral (the default) means the metric has no agreed-good direction (raw sizes, structural counts) and is left uncoloured. Neutral is skipped on the wire, so a neutral metric serializes exactly as the old Option<String> form did: the direction field absent.

Variants

Neutral

LowerBetter

HigherBetter

Implementations

impl Direction

pub fn is_neutral(&self) -> bool

true for the default (no opinion) — used by serde to omit the field.

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Direction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Direction

impl Debug for Direction

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

Formats the value using the given formatter.

impl Default for Direction

fn default() -> Direction

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Direction

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Direction

impl PartialEq for Direction

fn eq(&self, other: &Direction) -> 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 Serialize for Direction

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
