Description

The code generated from our swagger file fails to compile with multiple errors.

Swagger-codegen version

Tried with current stable release and with recent nightly (swagger-codegen-cli-2.4.0-20180511.013033-251.jar)

Swagger declaration file content or url

https://github.com/aeternity/epoch/blob/master/config/swagger.yaml

Command line used for generation

java -jar ~/Downloads/swagger-codegen-cli-2.4.0-20180511.013033-251.jar generate -i ../aeternity/src/epoch/config/swagger.yaml -l rust-server

Steps to reproduce

java -jar ~/Downloads/swagger-codegen-cli-2.4.0-20180511.013033-251.jar generate -i ../aeternity/src/epoch/config/swagger.yaml -l rust-server
cargo check

fails with multiple errors like

Suggest a fix/enhancement

Start with the linked swagger.yaml and reproduce the issue using the documented swagger-codegen CLI command with the rust-server generator. Run cargo check on the generated project and trace the duplicate get_tx/get_txs definitions; done means the generated Rust code compiles without the reported errors.
