From ffd2f3d9bfef6c8121983a286697162fd63cc3c1 Mon Sep 17 00:00:00 2001 From: Tunay Engin Date: Mon, 19 Jan 2026 01:48:12 +0300 Subject: [PATCH 1/4] Add TypedPath and ApiError derive macros with typed routing Introduces the TypedPath trait and derive macro for type-safe, declarative route definitions and URL generation. Adds a Typed extractor for ergonomic path parameter extraction. Implements the ApiError derive macro for declarative error handling. Refactors test client into rustapi-testing crate, updates re-exports, and adds integration and derive macro tests. Updates documentation and examples to showcase new features. --- Cargo.lock | 1 + README.md | 23 ++ crates/rustapi-core/src/app.rs | 5 + crates/rustapi-core/src/extract.rs | 51 +++ crates/rustapi-core/src/lib.rs | 13 +- crates/rustapi-core/src/request.rs | 4 +- crates/rustapi-core/src/router.rs | 12 +- crates/rustapi-core/src/typed_path.rs | 13 + crates/rustapi-extras/src/cors/mod.rs | 8 +- crates/rustapi-macros/src/lib.rs | 257 ++++++++++++++ crates/rustapi-rs/examples/typed_path_poc.rs | 56 +++ crates/rustapi-rs/src/lib.rs | 6 + crates/rustapi-rs/tests/api_error_derive.rs | 40 +++ crates/rustapi-rs/tests/typed_path_derive.rs | 43 +++ crates/rustapi-testing/Cargo.toml | 1 + .../src/client.rs} | 328 +----------------- crates/rustapi-testing/src/lib.rs | 2 + docs/cookbook/theme/custom.css | 2 +- tasks.md | 225 ------------ tests/integration/main.rs | 40 ++- 20 files changed, 565 insertions(+), 565 deletions(-) create mode 100644 crates/rustapi-core/src/typed_path.rs create mode 100644 crates/rustapi-rs/examples/typed_path_poc.rs create mode 100644 crates/rustapi-rs/tests/api_error_derive.rs create mode 100644 crates/rustapi-rs/tests/typed_path_derive.rs rename crates/{rustapi-core/src/test_client.rs => rustapi-testing/src/client.rs} (53%) delete mode 100644 tasks.md diff --git a/Cargo.lock b/Cargo.lock index 3a828a4..db3bc07 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3244,6 +3244,7 @@ dependencies = [ "hyper-util", "proptest", "reqwest", + "rustapi-core", "serde", "serde_json", "thiserror 1.0.69", diff --git a/README.md b/README.md index 0a852a7..c087c18 100644 --- a/README.md +++ b/README.md @@ -211,8 +211,31 @@ rustapi-rs = { version = "0.1.9", features = ["jwt", "cors", "toon", "ws", "view | `audit` | GDPR/SOC2 audit logging | | `full` | All features enabled | + +### ✨ New Ergonomic Features + +**Declarative Error Handling:** +```rust +#[derive(ApiError)] +pub enum UserError { + #[error(status = 404, message = "User not found")] + NotFound(i32), + #[error(status = 400, code = "validation_error")] + InvalidInput(String), +} +``` + +**Fluent Testing:** +```rust +let client = TestClient::new(app);

Updated imports and re-exports to support the new macro location. Added rustapi-testing as a dev-dependency and updated test code to use it. Minor code cleanups and #[allow(dead_code)] annotations were added to suppress warnings in test and property test code. Removed the semver check job from the CI workflow. --- .github/workflows/ci.yml | 12 +- Cargo.lock | 1 + crates/rustapi-core/Cargo.toml | 1 + crates/rustapi-core/src/interceptor.rs | 31 ---- crates/rustapi-core/src/router.rs | 6 +- crates/rustapi-core/src/stream.rs | 20 +-- crates/rustapi-core/tests/streaming_test.rs | 6 +- crates/rustapi-macros/src/api_error.rs | 86 +++++++++++ crates/rustapi-macros/src/lib.rs | 151 ++------------------ crates/rustapi-rs/Cargo.toml | 2 + crates/rustapi-rs/src/lib.rs | 1 + crates/rustapi-validate/src/v2/tests.rs | 3 + 12 files changed, 126 insertions(+), 194 deletions(-) create mode 100644 crates/rustapi-macros/src/api_error.rs diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 2989519..5faf93d 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -154,15 +154,5 @@ jobs: env: RUSTDOCFLAGS: -D warnings - semver: - name: SemVer Checks - runs-on: ubuntu-latest - steps: - - uses: actions/checkout@v4 - - name: Install Rust - uses: dtolnay/rust-toolchain@stable - - name: Install cargo-semver-checks - uses: taiki-e/install-action@cargo-semver-checks - - name: Check for breaking changes - run: cargo semver-checks check-release + diff --git a/Cargo.lock b/Cargo.lock index db3bc07..0bd6161 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3118,6 +3118,7 @@ dependencies = [ "prometheus", "proptest", "rustapi-openapi", + "rustapi-testing", "rustapi-validate", "serde", "serde_json", diff --git a/crates/rustapi-core/Cargo.toml b/crates/rustapi-core/Cargo.toml index 0b8841f..5417a87 100644 --- a/crates/rustapi-core/Cargo.toml +++ b/crates/rustapi-core/Cargo.toml @@ -70,6 +70,7 @@ rustapi-openapi = { workspace = true, default-features = false } [dev-dependencies] tokio = { workspace = true, features = ["macros", "rt-multi-thread"] } proptest = "1.4" +rustapi-testing = { workspace = true } [features] default = ["swagger-ui", "tracing"] swagger-ui = ["rustapi-openapi/swagger-ui"] diff --git a/crates/rustapi-core/src/interceptor.rs b/crates/rustapi-core/src/interceptor.rs index 88dcad2..46b602f 100644 --- a/crates/rustapi-core/src/interceptor.rs +++ b/crates/rustapi-core/src/interceptor.rs @@ -333,37 +333,6 @@ mod tests { } } - /// A request interceptor that modifies a header - #[derive(Clone)] - struct HeaderModifyingRequestInterceptor { - header_name: &'static str, - header_value: String, - } - - impl HeaderModifyingRequestInterceptor { - fn new(header_name: &'static str, header_value: impl Into) -> Self { - Self { - header_name, - header_value: header_value.into(), - } - } - } - - impl RequestInterceptor for HeaderModifyingRequestInterceptor { - fn intercept(&self, mut request: Request) -> Request { - // Store the value in extensions since we can't modify headers directly - // In a real implementation, we'd need mutable header access - request - .extensions_mut() - .insert(format!("{}:{}", self.header_name, self.header_value));
