Struct RegionEvidence

pub struct RegionEvidence {
    pub polygons: usize,
    pub holes: usize,
    pub emptied: bool,
}

What an operation did to produce a region.

Fields

polygons: usize

Number of disjoint polygons in the result.

holes: usize

Number of inner boundary components across all polygons.

emptied: bool

The operation consumed a non-empty input and produced nothing.

Distinguishes “eroded out of existence” or “disjoint operands” from “the input was already empty”, which a bare empty result cannot.

Trait Implementations

impl Clone for RegionEvidence

fn clone(&self) -> RegionEvidence

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RegionEvidence

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RegionEvidence

fn default() -> RegionEvidence

Returns the “default value” for a type.

impl PartialEq for RegionEvidence

fn eq(&self, other: &RegionEvidence) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
