我正在查看Graphql变异源代码，我看到了这段代码，我不知道该搜索什么，我在下面看到<T>和 type mutationFn = (
object: any,
ctx: any,
info: GraphQLResolveInfo
) => Promise<any> | any;
function resolveMaybeThunk<T>(thingOrThunk: Thunk<T>): T {
return typeof thingOrThunk === 'function' ? thingOrThunk() : thingOrThunk;
}
type MutationConfig = {
name: string,
description?: string,
deprecationReason?: string,
inputFields: Thunk<GraphQLInputFieldConfigMap>,
outputFields: Thunk<GraphQLFieldConfigMap<*, *>>,
mutateAndGetPayload: mutationFn,
};，这是什么？

包裹代码时该怎么办？
