pub const EMPTY_RESULT: &str = "the exact compiler's result is empty, and so is the mesh";Expand description
The DeviationContribution::detail of a boolean whose exact result is
empty and whose mesh is too (#326): nothing is left in either, so the
distance between them is certified 0, widened like any bound by the
readings and the rounding floor of the exact result’s report. The
bound is unbounded by name when the empty result is that of operands
flattened within a warped slab width. The exact compiler holds the
empty result internally and refuses it only as a root, so the report
cannot be measured against a B-rep; an empty exact result against a
mesh with triangles, or the reverse, is unbounded by name.
