Struct PolyRef 

pub struct PolyRef<'a> { /* private fields */ }

A borrowed reference to a polygon.

Implementations

impl<'a> PolyRef<'a>

pub fn rect(&self) -> Rect

pub fn num_holes(&self) -> usize

pub fn clockwise(&self) -> bool

pub fn exterior(&self) -> RingRef<'a>

pub fn hole_at(&self, index: usize) -> Option<RingRef<'a>>

pub unsafe fn from_raw(ptr: *const tg_poly) -> Option<Self>

Safety

The pointer must be valid for the lifetime 'a.

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

pub fn to_owned(&self) -> Result<Poly>
