Enum JoinStyle

#[non_exhaustive]
pub enum JoinStyle {
    Bevel,
    Miter {
        angle_limit: f64,
    },
    Round {
        max_segment_ratio: f64,
    },
}

How the outline turns a corner.

Named in kernel vocabulary rather than re-exported from the backend so the choice stays a kernel contract if the backend is ever replaced.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Bevel

Cut the corner off with a straight segment. Bounded by construction.

Miter

Extend the offset edges until they meet, limited by angle_limit radians: sharper corners than this fall back to a bevel.

The limit is required rather than defaulted because an unlimited miter on a near-degenerate corner produces an arbitrarily distant spike.

Fields

angle_limit: f64

Round

Approximate a circular arc, with max_segment_ratio bounding segment length over arc radius.

Fields

max_segment_ratio: f64

Trait Implementations

impl Clone for JoinStyle

fn clone(&self) -> JoinStyle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JoinStyle

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

Formats the value using the given formatter.

impl PartialEq for JoinStyle

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