Struct DoubleValue 

pub struct DoubleValue {
    pub value: f64,
    pub provenance: Provenance,
}

An observed f64 value.

Fields

value: f64

The observed number. NaN is normalised before fingerprinting.

provenance: Provenance

Shared provenance.

Implementations

impl DoubleValue

pub fn new( name: ParameterName, value: f64, generator: Option<GeneratorInfo>, ) -> Self

Construct, computing the fingerprint and stamping “now”.

pub fn new_at( name: ParameterName, value: f64, generator: Option<GeneratorInfo>, now: Timestamp, ) -> Self

Construct with an explicit timestamp (deterministic in tests).

pub fn fingerprint_of(name: &ParameterName, value: f64) -> Fingerprint

Canonical fingerprint for a double value. NaN collapses to the canonical quiet-NaN pattern first.

Trait Implementations

impl Clone for DoubleValue

fn clone(&self) -> DoubleValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DoubleValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DoubleValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DoubleValue

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
