Struct webrender::prim_store::PolygonKey

pub struct PolygonKey {
    pub point_count: u8,
    pub points: [PointKey; 32],
    pub fill_rule: FillRule,
}

To create a fixed-size representation of a polygon, we use a fixed number of points. Our initialization method restricts us to values <= 32. If our constant POLYGON_CLIP_VERTEX_MAX is > 32, the Rust compiler will complain.

Fields

point_count: u8

points: [PointKey; 32]

fill_rule: FillRule

Implementations

impl PolygonKey

pub fn new(points_layout: &Vec<LayoutPoint>, fill_rule: FillRule) -> Self

Trait Implementations

impl Clone for PolygonKey

fn clone(&self) -> PolygonKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PolygonKey

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

Formats the value using the given formatter.

impl Hash for PolygonKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl InternDebug for PolygonKey

fn on_interned(&self, _uid: ItemUid)

impl MallocSizeOf for PolygonKey

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for PolygonKey

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for PolygonKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for PolygonKey

impl Eq for PolygonKey

impl StructuralPartialEq for PolygonKey
