Enum Fill 

#[repr(u8)]
pub enum Fill {
    NonZero = 0,
    EvenOdd = 1,
}

Describes the rule that determines the interior portion of a shape.

This is only relevant for self-intersecting paths (e.g. a hourglass shape). For non-self-intersecting paths, both rules produce the same result.

Variants

NonZero = 0

Non-zero fill rule.

All regions where the winding number of the path is not zero will be filled. This is generally more correct, but can be more expensive to implement in renderers. This matches the default behavior of the web canvas, and is the default value.

EvenOdd = 1

Even-odd fill rule.

All regions where the winding number of the path is odd will be willed. The most common use case for this rule is as an optimisation when the paths are known to not be self-intersecting. There may also be cases where this rendering is desired. This can be implemented more efficiently than even-odd, as the winding number state can be stored in only one bit (and so the winding numbers for several pixels can be packed extremely efficiently).

Trait Implementations

impl Clone for Fill

fn clone(&self) -> Fill

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fill

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

Formats the value using the given formatter.

impl Default for Fill

fn default() -> Fill

Returns the “default value” for a type.

impl From<Fill> for Style

fn from(fill: Fill) -> Style

Converts to this type from the input type.

impl From<Fill> for StyleRef<'_>

fn from(fill: Fill) -> StyleRef<'_>

Converts to this type from the input type.

impl PartialEq for Fill

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

impl Copy for Fill

impl Eq for Fill

impl StructuralPartialEq for Fill
