Struct MetricDelta 

pub struct MetricDelta {
    pub before: f64,
    pub after: f64,
    pub delta: f64,
}

How one metric moved between parent and child.

Fields

before: f64

The parent’s value.

after: f64

The child’s value.

delta: f64

after - before. Signed on purpose: whether that is good news depends on the objective’s direction, which the move does not presume to know.

Trait Implementations

impl Clone for MetricDelta

fn clone(&self) -> MetricDelta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetricDelta

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MetricDelta

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MetricDelta

fn eq(&self, other: &MetricDelta) -> 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 MetricDelta

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
