Struct LandingEvidence 

pub struct LandingEvidence { /* private fields */ }

The landing at one end of a flight or run.

direction is the horizontal direction leaving the subject at that end (back down the flight’s direction at its bottom, on at its top); edge the position along it of the end’s arrival line: the first riser at a flight’s bottom, the last riser at its top, a run’s end. A landing’s positions are along the same direction, so its depth is its far side less the edge. landing is None when no candidate’s level surface at the end’s elevation meets the end: nothing selected carries it.

Implementations

impl LandingEvidence

pub fn try_new( request: LandingRequest, direction: MetricDirection, edge: ElevationInterval, landing: Option<Landing>, evidence: Evidence, ) -> Result<Self, WalkingSurfaceError>

The landing answering request. The carrier must be the subject or a requested candidate, and a measured landing’s far side must lie decidably beyond the edge; the evidence is exact exactly when every position is a point.

pub fn request(&self) -> &LandingRequest

The request this answers.

pub fn direction(&self) -> MetricDirection

The horizontal direction leaving the subject at the end.

pub fn edge(&self) -> ElevationInterval

Position of the end’s arrival line along the leaving direction.

pub fn landing(&self) -> Option<&Landing>

The landing, or None when nothing requested carries one.

pub fn depth(&self) -> Option<MeasuredInterval>

The landing’s depth along the leaving direction, from the arrival line to its far side, when its extent was measured.

pub fn width(&self) -> Option<MeasuredInterval>

The landing’s width across the leaving direction, when its extent was measured.

pub fn evidence(&self) -> &Evidence

Reviewable provenance of the measurement.
