Enum MorphologyMode 

#[non_exhaustive]
pub enum MorphologyMode {
    Exact,
    Fast {
        budget: f64,
    },
}

How the disc morphology (Region::erode_inner_with and its siblings) is computed (#330).

Both modes keep the stated side: an inner result lies within the exact disc morphology, an outer one holds it, and MorphologyBound says by how much they may differ.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Exact

The exact route of Region::erode_inner and its siblings, bit for bit. Its cost grows with the square of the corners along walls of teeth closer together than about a tenth of the radius. The choice of a CAD kernel.

Fast

The set is summed with its notches filled by chords across its outermost corners, where that makes the sum at most budget larger (in metres, for a disc of the radius): each wall of teeth costs about its corners. The excess actually taken, at most budget and often far less, is added to the MorphologyBound::deviation and reported by Region::excess. The choice of a rule engine.

Fields

budget: f64

The greatest excess a filled notch may add.
