Struct PlanLength 

pub struct PlanLength { /* private fields */ }

A measured plan length in metres, with its evidence.

Implementations

impl PlanLength

pub fn try_new( lower: f64, upper: f64, evidence: Evidence, ) -> Result<Self, PlanSpanError>

A length known to lie in [lower, upper].

The evidence is exact exactly when the bounds coincide: an interval cannot be exact evidence, and a point cannot be approximate.

pub fn lower_metres(&self) -> f64

Shortest the length can be, in metres.

pub fn upper_metres(&self) -> f64

Longest the length can be, in metres.

pub fn is_exact(&self) -> bool

Whether the length is known exactly.

pub fn evidence(&self) -> &Evidence

Reviewable provenance of the measurement.
