Implementations

impl Paths64

pub fn new(paths: impl Into<Vec<Path64>>) -> Self

New collection from any Into<Vec>. / 由 Into<Vec> 构造。

pub fn as_slice(&self) -> &[Path64]

Slice of all paths. / 全部路径切片。

pub fn path(&self, index: usize) -> &Path64

Borrow one path by index. / 按下标借用路径。

pub fn is_empty(&self) -> bool

True if there are zero paths. / 是否无路径。

pub fn len(&self) -> usize

Path count. / 路径条数。

pub fn add_path(&mut self, path: Path64)

Push one path. / 追加一条路径。

pub fn add_paths(&mut self, paths: impl IntoIterator<Item = Path64>)

Extend with many paths. / 追加多条。

pub fn to_vec(&self) -> Vec<Path64>

Clone all paths into a vector. / 克隆为 Vec。

pub fn translate(&self, dx: i64, dy: i64) -> Self

Per-path translate with i64 deltas. / 逐路径平移（i64）。

pub fn scale(&self, sx: f64, sy: f64) -> Self

Per-path scale (f64 factors, 0 → 1). / 逐路径缩放。

impl Paths64

pub fn simplify(&self, epsilon: f64, is_open_path: bool) -> LazyPaths64

Simplifies every path. / 对每条路径做简化。

pub fn inflate( &self, delta: f64, join_type: JoinType, end_type: EndType, miter_limit: f64, ) -> LazyPaths64

Offsets (inflates/deflates) all paths by delta using join/end rules.

按连接/端点规则对全部路径做 delta 偏移（膨胀或收缩）。

pub fn to_pathsd(&self) -> LazyPathsD

Converts all paths to PathD blobs. / 将全部路径转为双精度。

impl Paths64

pub fn minkowski_sum( &self, pattern: &Path64, is_closed: bool, fillrule: ClipperFillRule, ) -> LazyPaths64

Minkowski sum against each path with fill rule. / 对多条路径做闵可夫斯基和（含填充规则）。

pub fn minkowski_diff( &self, pattern: &Path64, is_closed: bool, fillrule: ClipperFillRule, ) -> LazyPaths64

Minkowski difference with fill rule. / 闵可夫斯基差（含填充规则）。

impl Paths64

pub fn area(&self) -> f64

Sum of signed areas. / 各路径有向面积之和。
