- Trait-based plugin architecture - Support for request/response flows - Static binary builds with musl - Examples: simple, auth, rate-limit - CI/CD with GitHub Actions - justfile for task automation - Comprehensive documentation
- Remove redundant single-component path imports of tracing_subscriber from all example files - Update Makefile lint target to use --all-targets --all-features to match CI configuration and justfile This ensures make lint catches the same issues as CI clippy checks.
Update Minimum Supported Rust Version from 1.75.0 to 1.83.0 due to dependency requirements (icu_collections v2.1.1 requires rustc 1.83+). Updated in: - Cargo.toml: rust-version field - README.md: version badge and policy section - CONTRIBUTING.md: prerequisites section - .github/workflows/test.yaml: CI test matrix
Updated documentation examples to use the correct r#continue raw identifier syntax instead of continue_ for the HttpResponse field. This matches the protobuf-generated code where continue is a Rust reserved keyword. Fixed in src/lib.rs: - Quick Start example (line 72) - Authentication Plugin example pass-through (line 131) - Authentication Plugin short-circuit (line 139) All doctests now pass.
Renamed .cargo-deny.toml to deny.toml for proper detection by cargo-deny. Updated license configuration to: - Add missing permissive licenses (0BSD, Unicode-3.0, CDLA-Permissive-2.0) - Remove deprecated configuration options (vulnerability, copyleft, deny) - Add explicit documentation that all allowed licenses are compatible with Apache-2.0 - Simplify configuration to work with latest cargo-deny version All allowed licenses are permissive (non-copyleft) and compatible with the Apache-2.0 license used by this SDK.

Implements a complete Rust SDK for building
mcpdplugins, following the same patterns established in the Go, Python, and .NET SDKs while adhering to Rust idioms and best practices.
