描述

I have a simple interface called Filters

export interface Filters {
  search: string;
}

And I'm trying to use it like with selectorFamily like that: selectorFamily<Patient[], Filters> I'm getting typescript error

Type 'Filters' does not satisfy the constraint 'SerializableParam'. Type 'Filters' is not assignable to type 'Readonly<{ [key: string]: SerializableParam; }>'. Index signature is missing in type 'Filters'.ts(2344)

If I simply extract the interface selectorFamily<Patient[], { search: string }> it works, but I would happy to not do it

研究方向
Investigate the Recoil type definitions in the repository, specifically the `selectorFamily` function and the `SerializableParam` constraint. Look at how generics are constrained and whether the interface can be made to satisfy the constraint without an index signature. Check existing comments for suggested workarounds or maintainer input on whether this is intended behavior.
