Struct Path

pub struct Path { /* private fields */ }

Implementations

impl Path

pub fn iter(&self) -> impl Iterator<Item = Path> + '_

pub fn is_closed(&self) -> bool

pub fn find_outer_shell(&self) -> Option<Path>

智能地查找并返回代表最外层轮廓的子路径。

这个方法会优先使用快速的“面积最大”启发式算法。 如果该算法无法找到结果，则会回退到更精确但更慢的“几何包含”算法。

Trait Implementations

impl Clone for Path

fn clone(&self) -> Path

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Path

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

Formats the value using the given formatter.

impl Display for Path

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

Formats the value using the given formatter.

impl From<&(Coord2, Vec<(Coord2, Coord2, Coord2)>)> for Path

fn from(value: &SimpleBezierPath) -> Self

Converts to this type from the input type.

impl From<&Path> for SimpleBezierPath

fn from(path: &Path) -> SimpleBezierPath

Converts to this type from the input type.

impl From<&Vec<Curve<Coord2>>> for Path

fn from(value: &Vec<Curve<Coord2>>) -> Self

Converts to this type from the input type.

impl From<Path> for Path

fn from(value: Path) -> Self

Converts to this type from the input type.

impl FromStr for Path

type Err = PathError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl<'a> IntoIterator for &'a Path

为我们自己的 Path 类型的引用实现 IntoIterator trait。 这使得可以直接在 for 循环中使用 &Path。

fn into_iter(self) -> Self::IntoIter

定义如何从一个 &Path 创建出我们的 SubpathIter 迭代器。

type Item = Path

The type of the elements being iterated over.

type IntoIter = SubpathIter<'a>

Which kind of iterator are we turning this into?
