isEdge()
测试一个对象是否可以用作 Edge。在 TypeScript 中,这是一个类型保护,如果返回 true,它将缩小你传递给 Edge 的任何内容的类型。
¥Test whether an object is usable as an Edge. In TypeScript
this is a type guard that will narrow the type of whatever you pass in to
Edge if it returns true.
import { isEdge } from '@xyflow/react';
const edge = {
id: 'edge-a',
source: 'a',
target: 'b',
};
if (isEdge(edge)) {
// ...
