Struct Ring 

pub struct Ring { /* private fields */ }

An owned closed ring.

Implementations

impl Ring

pub fn rect(&self) -> Rect

pub fn num_points(&self) -> usize

pub fn point_at(&self, index: usize) -> Option<Point>

pub fn points(&self) -> &[Point]

pub fn num_segments(&self) -> usize

pub fn segment_at(&self, index: usize) -> Option<Segment>

pub fn convex(&self) -> bool

pub fn clockwise(&self) -> bool

pub fn area(&self) -> f64

pub fn perimeter(&self) -> f64

pub fn nearest_segment<RD, SD, I>( &self, rect_dist: RD, seg_dist: SD, iter: I, ) -> bool

where RD: FnMut(Rect) -> (f64, bool), SD: FnMut(Segment) -> (f64, bool), I: FnMut(Segment, f64, usize) -> bool,

Iterates segments by distance. Returns true if completed.

pub fn new(points: &[Point]) -> Result<Self>

pub fn new_ix(points: &[Point], ix: IndexKind) -> Result<Self>

pub unsafe fn from_raw(ptr: *mut tg_ring) -> Option<Self>

Safety

The pointer must be valid and not owned elsewhere.

pub fn as_ptr(&self) -> *const tg_ring

pub fn into_raw(self) -> *mut tg_ring

pub fn copy(&self) -> Result<Self>

pub fn clone_ref(&self) -> Result<Self>

pub fn memsize(&self) -> usize

pub fn index_spread(&self) -> i32

pub fn index_num_levels(&self) -> i32

pub fn index_level_num_rects(&self, level: i32) -> i32

pub fn index_level_rect(&self, level: i32, rect_idx: i32) -> Rect

pub fn iter_points(&self) -> impl Iterator<Item = Point> + '_

pub fn iter_segments(&self) -> impl Iterator<Item = Segment> + '_

pub fn line_search<F>(&self, line: &Line, iter: F)

where F: FnMut(Segment, usize, Segment, usize) -> bool,

Return false to stop iteration.

pub fn ring_search<F>(&self, other: &Ring, iter: F)

where F: FnMut(Segment, usize, Segment, usize) -> bool,

Return false to stop iteration.
