Announcing RBS support for AWS SDK for Ruby V3 | AWS Developer Tools Blog

RBS is a language to describe the structure of Ruby programs. We are happy to announce that AWS SDK for Ruby V3 now supports RBS type signatures! RBS support is released in aws-sdk-core version 3.191.0 and in every service gem (such as aws-sdk-s3) that depends on this version of core. RBS signatures are currently code generated from the API models for the API client, errors, resource models, types/structures, and waiters.
