Struct StrokeRec 

pub struct StrokeRec { /* private fields */ }

描边参数，描述如何将路径转为描边轮廓。 Stroke parameters - describes how to expand a path to a stroke outline.

用于 apply_to_path 将路径转换为描边后的填充路径。 Used with apply_to_path to convert a path to a stroked fill equivalent.

Implementations

impl StrokeRec

pub fn new_fill() -> Self

创建填充样式（无描边）。Creates fill style (no stroke).

pub fn new_hairline() -> Self

创建极细线样式。Creates hairline style (1-pixel stroke).

pub fn new_stroke(width: f32, stroke_and_fill: bool) -> Self

创建描边样式。Creates stroke style with given width.

pub fn set_fill(&mut self)

设置为填充样式。Sets to fill style.

pub fn set_hairline(&mut self)

设置为极细线。Sets to hairline style.

pub fn set_stroke_style(&mut self, width: f32, stroke_and_fill: bool)

设置描边宽度。Sets stroke width (width=0 may switch to fill/hairline).

pub fn set_cap(&mut self, cap: StrokeCap)

设置线端样式。Sets line cap (Butt, Round, Square).

pub fn set_join(&mut self, join: StrokeJoin)

设置转角连接样式。Sets line join (Miter, Round, Bevel).

pub fn set_stroke_params( &mut self, cap: StrokeCap, join: StrokeJoin, miter_limit: f32, )

设置描边端点与转角参数。Sets cap, join, and miter limit.

pub fn cap(&self) -> StrokeCap

线端样式。Returns line cap.

pub fn join(&self) -> StrokeJoin

转角连接样式。Returns line join.

pub fn miter_limit(&self) -> f32

Miter 限制（尖角最长延伸比）。Returns miter limit.

pub fn style(&self) -> StrokeStyle

当前样式。Returns current style (hairline/fill/stroke).

pub fn width(&self) -> f32

描边宽度。Returns stroke width.

pub fn inflation_radius(&self) -> f32

膨胀半径（用于边界计算）。Inflation radius for bounds.

pub fn apply_to_path(&self, path: &Path) -> Option<Path>

将描边参数应用到路径，返回描边后的填充路径。 Applies stroke to path, returning the stroked outline as a fill path.

若样式为 fill/hairline 则返回 None。 Returns None if style is fill or hairline (no expansion).

Trait Implementations

impl Default for StrokeRec

fn default() -> Self

Returns the “default value” for a type.
