Struct StrokeStyle 

pub struct StrokeStyle {
    pub width: f64,
    pub cap: LineCap,
    pub join: LineJoin,
}

logical-unit stroke style, with explicit caps, joins and dash geometry.

Defaults to width one, butt caps and a miter join with limit four. Width must be finite and nonnegative; zero emits no outline. This bounded first slice accepts paths of at most MAX_STROKE_VERBS verbs. Curves expand directly into fill outlines; Styled trim/dash use exact source-curve splitting first. Nonzero widths and segment lengths require 1e-30..=1e30; coordinates require absolute magnitude at most 1e30, and the width must exceed local rounding noise. Round outlines use kurbo’s cubic circular approximation, not exact circles. Move-only and zero-length subpaths emit no dot, including with round caps.

Fields

width: f64

Full logical width; zero preserves layout but draws no stroke.

cap: LineCap

The same cap for both ends of each open subpath.

join: LineJoin

Connection at each nondegenerate corner, including closed seams.
