[rust-server] lacks collectionFormat support
Created by: bjgill
Description
See https://github.com/swagger-api/swagger-codegen/issues/8173#issuecomment-388855190. I no longer remember what the problem was, but it seems as if we generate invalid Rust when faced with a collectionFormat.
e.g.
parameters:
- in: query
name: color
type: array
collectionFormat: csv
items:
type: string(Note: this part of a set of issues from swagger-codegen. I didn't fix this as part of the move to openapi-generator. Thus I strongly suspect rust-server in openapi-generator also suffers the same problem. I'm not planning on working on this at the moment - contributions gratefully welcomed)
