[dependabot]

Updates the requirements on rbs to permit the latest version.

Release notes

Sourced from rbs's releases.

4.1.3

Release note

Miscellaneous

• Don't use Clang nullability qualifiers in strict ISO C mode (#3074, Backported in #3075)
• Avoid eagerly inspecting call traces in type assertions (#3073, Backported in #3076)

4.1.2

Release note

Miscellaneous

• Keep GC disabled during GC_test#test_stress_and_stress= (#3061)
• Fix GC_test#test_enable leaving GC disabled for the rest of the suite (#3059)

4.1.1

Release note

Library changes

• Include the trailing ? in a keyword key's symbol location (#3043)
• Mark type_name as optional on the alias annotations (#3039)

Miscellaneous

• Fix template drift for ext/rbs_extension/ast_translation.c (#3038)

4.1.1.pre.1

Release note

Library changes

• Include the trailing ? in a keyword key's symbol location (#3043)
• Mark type_name as optional on the alias annotations (#3039)

Miscellaneous

• Fix template drift for ext/rbs_extension/ast_translation.c (#3038)

4.1.0

Release note

RBS 4.1 ships with JRuby support. The RBS parser is written in plain C without depending on the Ruby C API, so it is compiled to WebAssembly and runs on a Wasm runtime, with the parsed AST serialized in a binary format and decoded into RBS objects. The full test suite runs on JRuby in CI.

The inline RBS syntax gets three new features: singleton method definitions (def self.), the module-self constraint, and instance variable annotations in module declarations. Note that RBS inline is still experimental and may change in future releases.

This release also introduces RBS::Rewriter, an API to edit RBS source text while preserving the surrounding content, which rbs annotate is now built on. Parsing performance is improved by interning type names in a shared trie and reducing allocations per node.

RBS::Prototype::Runtime, the RDoc plugin parser, and the top-level float type alias are deprecated in this release.
