Description

I had some code that used to work on 5.4.0 and now it doesn't. I traced the issue down to some change in the implementation of the usage of oneOf, where previously swagger::OneOf<A,B> was generated, now a new model is generated, but that new model is empty.

openapi-generator version

Works on 5.4.0 and does not since 6.0.

OpenAPI declaration file content or url

I'll provide a full gist, but shortly these are the interesting bits:

openapi: 3.0.3
...
components:
schemas:
Test:
type: objectproperties:
something:
oneOf:
- type: string
- type: integer

Before:

pub something:Option<swagger::OneOf2<String,i32>>,

After:

pub something:Option<models::TestSomething>,
...
#[derive(Debug,Clone,PartialEq, serde::Serialize, serde::Deserialize, validator::Validate)]#[cfg_attr(feature = "conversion", derive(frunk::LabelledGeneric))]pubstructTestSomething{}
Generation Details
generate-710:
docker run --rm \
-v $(PWD):/local openapitools/openapi-generator-cli:v7.1.0 generate \
-i /local/test.yaml \
--generator-name rust-server \
--output /local/openapi \
--global-property models,modelDocs=false,supportingFiles
mv openapi/src/models.rs test-710.rs
rm -rf openapi
Steps to reproduce

See the Gist and then make generate-540 generate-710 generate-latest

Related issues/PRs

This looks like it might be related:

#13538

Suggest a fix

It seems that generating intermediate models for nested properties is a good idea, just that there should probably be some heuristic to detect when the nested type is a oneOf and use a different path.

                  It seems that generating intermediate models for nested properties is a good idea, just that there should probably be some heuristic to detect when the nested type is a oneOf and use a different path.

                      I had some code that used to work on 5.4.0 and now it doesn't. I traced the issue down to some change in the implementation of the usage of oneOf, where previously swagger::OneOf<A,B> was generated, now a new model is generated, but that new model is empty.
