Don't inline generics

[firstdorsal]

Hi!
Currently i have this generic return type:

#[derive(Serialize, Deserialize, ToSchema, Clone, Debug)]
pub struct ApiResponse<T> {
    pub message: String,
    pub status: ApiResponseStatus,
    pub data: Option<T>,
}

and then for example:

#[derive(Serialize, Deserialize, ToSchema, Clone)]
pub struct ListStorageLocationsRequestBody {
    pub sort_by: Option<ListStorageLocationsSortBy>,
    pub sort_order: Option<SortDirection>,
}

#[derive(Serialize, Deserialize, ToSchema, Clone)]
pub struct ListStorageLocationsResponseBody {
    pub storage_locations: Vec<StorageLocationListItem>,
}

#[derive(Serialize, Deserialize, ToSchema, Clone)]
pub enum ListStorageLocationsSortBy {
    CreatedTime,
    ModifiedTime,
    Name,
}

That then generates this inlined schema:

            "ApiResponse_ListStorageLocationsResponseBody": {
                "type": "object",
                "required": ["message", "status"],
                "properties": {
                    "data": {
                        "type": "object",
                        "required": ["storage_locations"],
                        "properties": {
                            "storage_locations": {
                                "type": "array",
                                "items": { "$ref": "#/components/schemas/StorageLocationListItem" }
                            }
                        }
                    },
                    "message": { "type": "string" },
                    "status": { "$ref": "#/components/schemas/ApiResponseStatus" }
                }
            },

the inner type is also present, but not used:

"ListStorageLocationsResponseBody": {
                "type": "object",
                "required": ["storage_locations"],
                "properties": {
                    "storage_locations": {
                        "type": "array",
                        "items": { "$ref": "#/components/schemas/StorageLocationListItem" }
                    }
                }
            },

I would like it to not inline structs generally, especially here I would like it to look like this, else code generation is very messy.

            "ApiResponse_ListStorageLocationsResponseBody": {
                "type": "object",
                "required": ["message", "status"],
                "properties": {
                    "data": { "$ref": "#/components/schemas/ListStorageLocationsResponseBody" },
                    "message": { "type": "string" },
                    "status": { "$ref": "#/components/schemas/ApiResponseStatus" }
                }
            },

I tried out .schema_collect(...) from https://github.com/juhaku/utoipa/tree/master/utoipa-config but couldn't get it to work.

Can this be done?

Thank you!
