Lazy reasons preserve error construction and message evaluation on the rejection path only.
导入
ts
import type { BreakReason } from '@jangts/agent-core/support';js
/** @typedef {import('@jangts/agent-core/support').BreakReason} BreakReason */其他公开入口：@jangts/agent-core、@jangts/agent-core/types、@jangts/agent-core/structs、@jangts/agent-core/support。
定义
ts
type BreakReason = Error | string | (() => Error | string);联合分支结构
使用示例
- 拒绝检查、首个匹配与顺序处理：使用真实清单表达多项检查和枚举分发；单个普通判断仍可直接使用 if。
一个明确的拒绝
入门 · Node.js
ts
import { Support } from '@jangts/agent-core';
const input = '你好';
Support.breakWhile(!input.trim(), '问题不能为空');
console.log(input);js
import { Support } from '@jangts/agent-core';
const input = '你好';
Support.breakWhile(!input.trim(), '问题不能为空');
console.log(input);有依赖关系的检查按序求值
配置 · Node.js
ts
import { Support } from '@jangts/agent-core';
const input: unknown = { name: 'Ivan' };
Support.breakWhile([
{ occur: !input || typeof input !== 'object', error: '需要对象' },
{ occur: () => !('name' in (input as object)), error: '缺少 name' },
]);
console.log(input);js
import { Support } from '@jangts/agent-core';
const input = { name: 'Ivan' };
Support.breakWhile([
{ occur: !input || typeof input !== 'object', error: '需要对象' },
{ occur: () => !('name' in input), error: '缺少 name' },
]);
console.log(input);
