Struct OffsetEvidence

#[non_exhaustive]
pub struct OffsetEvidence {
    pub input_rings: usize,
    pub output_polygons: usize,
    pub output_holes: usize,
    pub collapsed: bool,
}

What an offset actually did.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

input_rings: usize

Rings supplied by the caller.

output_polygons: usize

Polygons in the result.

output_holes: usize

Inner boundary components across all result polygons.

collapsed: bool

The input was non-empty but the result is empty.

Distinguishes a region inset out of existence from an empty input, which a bare empty vector cannot express.

Trait Implementations

impl Clone for OffsetEvidence

fn clone(&self) -> OffsetEvidence

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OffsetEvidence

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

Formats the value using the given formatter.

impl PartialEq for OffsetEvidence

fn eq(&self, other: &OffsetEvidence) -> 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.
