Start with the reproduced swagger-codegen command and the failure at CodegenConfigLoader.java:42, then trace the entry from SwaggerCodegen.main that resolves generator names. Done means selecting rust no longer reports it as unavailable and the command reaches generation successfully; add or run a repository test covering this selection if one is identified.
