IoQueryHandle

何时使用

当你需要复用类型结构时使用此类型别名。

签名

IoQueryHandle<TData, TError>

属性

Name	Type
key	IoQueryKey
keyHash	KeyHash
fetch	(force?: boolean) => Promise<TData>
prefetch	() => Promise<void>
ensureData	() => Promise<TData>
invalidate	(refetch?: boolean) => void
cancel	() => void
reset	() => void
setData	(updater: TData | ((prev: TData | undefined) => TData)) => void
getData	() => TData | undefined
getState	() => IoQueryState<TData, TError>
getFlags	() => IoQueryDerivedFlags
isActive	boolean
observerCount	number
subscribe	(fn: (state: IoQueryState<TData, TError>) => void) => IoUnsubscribe
subscribeUpdate	(fn: (update: IoUpdate) => void) => IoUnsubscribe

最小示例

import type { IoQueryHandle } from '@iostore/store/query';

let value!: IoQueryHandle;
console.log(value);

常见误用

• 避免在用户文档中展开过于复杂的类型细节。
• 调整类型别名时注意下游兼容性。
