# Phase 8 Plan 2: Rustdoc Completion — Summary

**One-liner:** 补全 lib.rs crate-level 文档（含 3 个可运行 Quick Start 代码块），修复 cargo doc --no-deps 的 5 个 broken intra-doc link 警告。

## Tasks

| # | Name | Status | Commit | Files |
|---|------|--------|--------|-------|
| 1 | sqllog.rs Phase 7 API 的中文 rustdoc | Already present from Phase 7 | — | src/sqllog.rs (no changes needed) |
| 2 | lib.rs crate-level 文档重写 | Done | `b96d297` | src/lib.rs |
| 3 | 全局补漏，修复 cargo doc warnings | Done | `d92bb26` | src/parser.rs, src/sqllog.rs |

## Progress

- **Task 1:** Phase 7 已为 `exec_time()`, `row_count()`, `FromSqllog` 提供了完整的中文 rustdoc，无需修改。
- **Task 2:** 将 lib.rs 快速开始部分的 2 个旧示例替换为 3 个新 `# Examples`:
  1. 基础迭代 (LogParserBuilder + iter)
  2. 过滤慢查询 (filter_by_exec_time + exec_time)
  3. 批量导出 (iter + parse_meta)
- **Task 3:** 修复了 `src/parser.rs` 3 处和 `src/sqllog.rs` 1 处 broken intra-doc link 警告。

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 — Broken intra-doc links] Fixed 5 cargo doc warnings**

- **Found during:** Task 3
- **Issue:** `cargo doc --no-deps` 报告 5 个 `warning: unresolved link` — `[build]`, `[iter()]` (x2), `[SEL]`, `[ORA]` 被 rustdoc 解释为 intra-doc links
- **Fix:** `[build]` → `[Self::build]`, `[iter()]` → `[iter()](LogParser::iter)`, `[SEL]`/`[ORA]` → `` `[SEL]` `` 代码跨度
- **Files modified:** `src/parser.rs`, `src/sqllog.rs`

## Known Stubs

None found.

## Threat Flags

None — changes are documentation-only.

## Verification Results

- `cargo test --doc`: 8 passed, 0 failed
- `cargo doc --no-deps`: 0 warnings, 0 errors

## Success Criteria

- [x] `cargo test --doc` passes — 3 Quick Start examples compile and run
- [x] `cargo doc --no-deps` has no warnings — all pub items have docs

## Self-Check

- [x] src/lib.rs exists in worktree and contains 3 no_run Examples
- [x] Commit b96d297 exists: docs(08-documentation): rewrite lib.rs crate-level docs
- [x] Commit d92bb26 exists: docs(08-documentation): fix broken intra-doc links
- [x] cargo test --doc: 8 passed
- [x] cargo doc --no-deps: 0 warnings
