useIsMutating
useIsMutating 是一个可选的 Hook，它返回应用程序正在获取的 mutation 的 数量（对于全应用范围的加载指示器很有用）。
tsx
import { useIsMutating } from '@tanstack/vue-query'
// How many mutations are fetching?
const isMutating = useIsMutating()
// How many mutations matching the posts prefix are fetching?
const isMutatingPosts = useIsMutating({ mutationKey: ['posts'] })
import { useIsMutating } from '@tanstack/vue-query'
// How many mutations are fetching?
const isMutating = useIsMutating()
// How many mutations matching the posts prefix are fetching?
const isMutatingPosts = useIsMutating({ mutationKey: ['posts'] })
