Struct OpBuilder 

pub struct OpBuilder { /* private fields */ }

路径操作构建器，用于批量执行路径布尔运算。 Path operation builder, optimized for unioning/combining many paths.

底层为 pk::SkOpBuilder，与 Skia PathKit 行为一致。 Backed by pk::SkOpBuilder, matching Skia PathKit behavior.

用法：多次 add 后调用 resolve 得到最终结果。 Usage: call add multiple times, then resolve to get the final result.

Implementations

impl OpBuilder

pub fn new() -> Self

创建空构建器。Creates an empty builder.

pub fn add(&mut self, path: Path, op: PathOp) -> &mut Self

添加路径及对应操作（消费 Path，C++ 侧会拷贝几何）。 Adds a path with its boolean operation (consumes Path; native side copies geometry).

第一次 add 时相当于 (空路径 OP path)，后续每次为 (当前结果 OP path)。 First add: (empty OP path). Each subsequent: (current_result OP path).

pub fn add_ref(&mut self, path: &Path, op: PathOp) -> &mut Self

按引用添加路径（C++ 侧拷贝几何，Rust 侧不消费 Path）。 Adds path by reference (native side copies geometry).

复用同一路径时比 add(path.clone(), op) 更简洁。 Convenient when reusing the same path.

pub fn resolve(&mut self) -> Option<Path>

计算并返回所有路径运算的结果。Resolves all operations and returns the result.

调用后构建器会清空，可继续复用。 Builder is reset after resolve; can be reused.

Trait Implementations

impl Default for OpBuilder

fn default() -> Self

Returns the “default value” for a type.
