Feature request: How to export multiple types to the same file

[zhangrunzhao]

I only want to put two or more types into the user.ts file at the same time, is there a solution at present?

#[derive(Debug, Deserialize, TS)]
#[ts(export, export_to = "user.ts")]
struct LoginReq {
    username: String,
    pwd: String,
}


#[derive(Debug, Deserialize, TS)]
#[ts(export, export_to = "user.ts")]
struct RegisterReq {
    username: String,
    pwd: String,
}

This cannot be done currently. Setting multiple types' #[ts(export_to = "...")] to the same file path will result in the file being overwritten and contain only the last type to be exported.
Which type will be the one that remains? No way to know, that's a race condition.

Your options are:

• Set all your export_tos to a directory path (must end in a /)
• Set the EXPORT_TS_RS_DIR environment variable to a directory path and remove all export_tos
• Set each type's export_to to its own, unique, file path

You could also try out the experimental CLI being developed in #304 (After applying one of the suggestions in the previous comment). It doesn't yet have the feature you're asking for, but it does have an option to generate an index.ts file that re-exports all your types.

If this feature gets implemented it will be through the CLI, as it is currently impossible for the library to do this on its own

Hey @zhangrunzhao, I've been trying to figure out a way to implement this. Please take a look at #316!
