Enum FinderOptions 

#[non_exhaustive]
pub enum FinderOptions {
    NoIndex,
    YStripes,
    NoIndexFloatRaycast,
    NoIndexIntegerRaycast,
}

Finder build options for polygon acceleration indexes.

Compressed topo data (the tzf-dist default) always stores polygons as 1e5-scaled integer coordinates; the options only choose the acceleration index and the raycast flavor. The indexes operate directly in the scaled integer storage space, so FinderOptions::YStripes keeps the full memory savings of integer storage.

Default:

• FinderOptions::NoIndex

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.

NoIndex

Disable polygon acceleration indexes.

For compressed topo data this is equivalent to FinderOptions::NoIndexFloatRaycast.

YStripes

Use Y stripes index (recommended).

NoIndexFloatRaycast

Disable polygon acceleration indexes; segment endpoints are converted to f64 in registers during raycasting.

NoIndexIntegerRaycast

Disable polygon acceleration indexes and use an integer cross-product raycast, which snaps the query point to the 1e-5 grid (a semantic difference near polygon edges). Opt-in.
