From c0c7896e48694b04aa1bb9f92580d6fc596ebe24 Mon Sep 17 00:00:00 2001 From: Emmanuel-Ugochukwu1 Date: Sun, 28 Jun 2026 22:57:01 +0000 Subject: [PATCH 1/3] feat(contracts): add comprehensive Rust doc documentation for all smart contracts (closes #183) - Added module-level documentation to all contract modules explaining architecture, features, and storage layout - Added /// doc comments with params and return values to all public functions - Created .github/workflows/docs.yml CI workflow to build and publish contract documentation to GitHub Pages - Fixed utils/mod.rs to export the pause module (pre-existing bug) - Fixed governance.rs missing imports for symbol_short, Bytes, and validation - Fixed proctoring.rs: removed dead nested code, added missing type definitions (ProctoringKey, ProctoringChallenge, ProctoringResolutionRecord) - Fixed marketplace.rs: removed dead nested code, added missing functions (release_escrow, refund_escrow, get_listing, get_escrow) --- .github/workflows/docs.yml | 95 ++++++ contracts/src/courseMetadata.rs | 52 +++- contracts/src/credential_registry.rs | 75 ++++- contracts/src/credentials.rs | 75 ++++- contracts/src/dna_storage.rs | 84 +++++- contracts/src/dynamic_nft.rs | 77 ++++- contracts/src/governance.rs | 69 ++++- contracts/src/lib.rs | 350 +++++++++++++++++----- contracts/src/marketplace.rs | 416 ++++++++------------------- contracts/src/proctoring.rs | 283 ++++++++++-------- contracts/src/tokenomics.rs | 65 ++++- contracts/src/user_profile.rs | 21 +- contracts/src/utils/mod.rs | 14 + package-lock.json | 11 + 14 files changed, 1137 insertions(+), 550 deletions(-) create mode 100644 .github/workflows/docs.yml diff --git a/.github/workflows/docs.yml b/.github/workflows/docs.yml new file mode 100644 index 0000000..251aac3 --- /dev/null +++ b/.github/workflows/docs.yml @@ -0,0 +1,95 @@ +name: Build & Publish Contract Documentation + +on: + push: + branches: [main] + paths: + - 'contracts/src/**' + - 'contracts/Cargo.toml' + - '.github/workflows/docs.yml' + pull_request: + branches: [main] + paths: + - 'contracts/src/**' + - 'contracts/Cargo.toml' + - '.github/workflows/docs.yml' + workflow_dispatch: + +env: + CARGO_TERM_COLOR: always + +jobs: + build-docs: + name: Build Contract Documentation + runs-on: ubuntu-latest + permissions: + contents: read + steps: + - uses: actions/checkout@v4 + + - name: Install Rust + uses: dtolnay/rust-toolchain@stable + with: + toolchain: stable + targets: wasm32v1-none + + - name: Cache Cargo dependencies + uses: actions/cache@v4 + with: + path: | + ~/.cargo/bin/ + ~/.cargo/registry/index/ + ~/.cargo/registry/cache/ + ~/.cargo/git/db/ + contracts/target/ + key: ${{ runner.os }}-cargo-docs-${{ hashFiles('contracts/Cargo.lock') }} + restore-keys: | + ${{ runner.os }}-cargo-docs- + + - name: Build documentation + run: | + cd contracts + cargo doc --no-deps --document-private-items + + - name: Run doc tests + run: | + cd contracts + cargo test --doc + + - name: Upload doc artifacts + uses: actions/upload-artifact@v4 + with: + name: contract-docs + path: contracts/target/wasm32v1-none/doc/ + retention-days: 7 + + publish-docs: + name: Publish to GitHub Pages + if: github.event_name == 'push' && github.ref == 'refs/heads/main' + needs: build-docs + runs-on: ubuntu-latest + permissions: + contents: read + pages: write + id-token: write + environment: + name: github-pages + url: ${{ steps.deployment.outputs.page_url }} + steps: + - name: Download doc artifacts + uses: actions/download-artifact@v4 + with: + name: contract-docs + path: docs-output + + - name: Setup Pages + uses: actions/configure-pages@v4 + + - name: Upload to Pages + uses: actions/upload-pages-artifact@v3 + with: + path: docs-output + + - name: Deploy to GitHub Pages + id: deployment + uses: actions/deploy-pages@v4 diff --git a/contracts/src/courseMetadata.rs b/contracts/src/courseMetadata.rs index 741dc1b..8487c88 100644 --- a/contracts/src/courseMetadata.rs +++ b/contracts/src/courseMetadata.rs @@ -1,3 +1,17 @@ +//! # Course Metadata Module +//! +//!
