Struct TokenMeasurement 

pub struct TokenMeasurement {
    pub value: Option<u64>,
    pub provenance: MeasurementProvenance,
}

A token value which can remain unknown without conflating unknown and zero.

Fields

value: Option<u64>

Token count, or None when it was not available.

provenance: MeasurementProvenance

Estimator, provider component, or derivation provenance.

impl TokenMeasurement

pub const fn unknown() -> Self

Return an unknown token value.

pub fn provider(provider: &str, component: &str, value: Option<u64>) -> Self

Return a provider-reported component. Zero is intentionally retained.
