Struct Provenance 

pub struct Provenance {
    pub parameter: ParameterName,
    pub generated_at: Timestamp,
    pub generator: Option<GeneratorInfo>,
    pub fingerprint: Fingerprint,
}

Shared metadata attached to every Value.

Values of any kind carry the same provenance: the owning parameter, an observation timestamp, the optional generator tag, and the canonical fingerprint.

Fields

parameter: ParameterName

Name of the parameter this value observes.

generated_at: Timestamp

When the value was constructed.

generator: Option<GeneratorInfo>

How the value was produced, if known.

fingerprint: Fingerprint

Canonical fingerprint of (kind, parameter, value bytes).

Trait Implementations

impl Clone for Provenance

fn clone(&self) -> Provenance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Provenance

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Provenance

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Provenance

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Provenance

impl StructuralPartialEq for Provenance
