Struct tiny_skia::StrokeDash

pub struct StrokeDash { /* private fields */ }

A stroke dashing properties.

Contains an array of pairs, where the first number indicates an “on” interval and the second one indicates an “off” interval; a dash offset value and internal properties.

Guarantees

• The dash array always have an even number of values.
• All dash array values are finite and >= 0.
• There is at least two dash array values.
• The sum of all dash array values is positive and finite.
• Dash offset is finite.

Implementations

impl StrokeDash

pub fn new(dash_array: Vec<f32>, dash_offset: f32) -> Option<StrokeDash>

Creates a new stroke dashing object.

Trait Implementations

impl Clone for StrokeDash

fn clone(&self) -> StrokeDash

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StrokeDash

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

Formats the value using the given formatter.

impl PartialEq for StrokeDash

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