Enum Measure 

pub enum Measure {
    RegionExtent {
        axis: Axis,
    },
    BoxExtent {
        node: NodeId,
        axis: PlanAxis,
    },
    BoxHeight {
        node: NodeId,
    },
    DistanceXz {
        from: NodeId,
        to: NodeId,
    },
    DatumY {
        datum: DatumId,
    },
}

What an identity measures off the plan.

A small fixed vocabulary, spelled as a tagged union rather than as the spec’s box(<node>).extent.x string. The vocabulary is exactly the spec’s five; what changes is that a measure is parsed by serde instead of by a grammar this module would have had to write, own and document — so an unknown measure is an ordinary DW0100, a node it names is checked like every other reference, and the growth the spec’s marked judgement predicts is a variant rather than a second escaping rule. §9 records the departure.

Variants

RegionExtent

The whole region’s extent on one axis, in blocks.

Fields

axis: Axis

Which axis.

BoxExtent

One place’s footprint on one horizontal axis, in blocks.

Fields

node: NodeId

The place.

axis: PlanAxis

Which horizontal axis.

BoxHeight

One place’s headroom over its walk plane, in blocks. A sky-open place measures the courses of air its ceiling declares.

Fields

node: NodeId

The place.

DistanceXz

The horizontal distance between two places’ footprint centres, in blocks. Euclidean on x/z; the standoff a brief states between two things.

Fields

from: NodeId

One place.

to: NodeId

The other.

DatumY

A named ground plane’s world y.

Fields

datum: DatumId

The plane.
