## 🔧 Prerequisites


### 1. Install Rust


**All Platforms:**
```bash
# Install Rust using rustup

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Or on Windows, download and run rustup-init.exe

# From: https://rustup.rs/

```

**Verify Installation:**
```bash
rustc --version
cargo --version
```

**Windows-Specific Requirements:**

Choose one of the following toolchains:

**Option A: GNU Toolchain (Recommended for simplicity)**
- Requires: MinGW/MSYS2
- Install MSYS2: https://www.msys2.org/
- After installation, run in MSYS2 terminal:
  ```bash
  pacman -Syu

  pacman -S mingw-w64-x86_64-toolchain

  ```
- Add `C:\msys64\mingw64\bin` to your system PATH
- Set Rust toolchain: `rustup default stable-x86_64-pc-windows-gnu`

**Option B: MSVC Toolchain**
- Requires: Visual Studio 2017+ or Build Tools for Visual Studio
- Download: https://visualstudio.microsoft.com/downloads/
- Install "Desktop development with C++" workload
- Set Rust toolchain: `rustup default stable-x86_64-pc-windows-msvc`

### 2. Create crates.io Account


1. **Go to crates.io:**
   - Visit: https://crates.io/
   - Click "Log in with GitHub" (top right)
   - Authorize crates.io to access your GitHub account

2. **Get API Token:**
   - After logging in, go to: https://crates.io/me
   - Click "New Token"
   - Token name: `WOWSQL SDK Upload`
   - Copy the token (starts with `cargo_...`)
   - **Save it immediately** - you won't see it again!

3. **Configure Cargo:**
   ```bash
   cargo login YOUR_TOKEN_HERE

   ```
   
   This saves the token to `~/.cargo/credentials` (or `%USERPROFILE%\.cargo\credentials` on Windows).

   **Verify:**
   ```bash
   cargo owner --list

   ```

### 3. Verify Cargo.toml


Ensure `Cargo.toml` has all required fields:

```toml
[package]
name = "WOWSQL"
version = "1.0.0"
edition = "2021"
authors = ["WOWSQL Team <support@wowsql.com>"]
description = "Official Rust SDK for WOWSQL - MySQL Backend-as-a-Service with S3 Storage"
license = "MIT"
repository = "https://github.com/wowsql/wowsql-rust"
homepage = "https://wowsql.com"
documentation = "https://docs.rs/WOWSQL"
keywords = ["mysql", "database", "backend", "s3", "storage", "baas"]
categories = ["database", "web-programming"]
```

---

## 📝 Publishing Steps


### Step 1: Navigate to Rust SDK


```bash
cd sdk/rust
```

### Step 2: Clean and Build


```bash
# Clean previous builds

cargo clean

# Build in release mode

cargo build --release

# Check for warnings

cargo clippy -- -D warnings

# Check formatting

cargo fmt --check
```

### Step 3: Run Tests


```bash
# Run all tests

cargo test

# Run tests with output

cargo test -- --nocapture
```

### Step 4: Generate Documentation


```bash
# Generate docs locally

cargo doc --no-deps --open

# Verify documentation builds

cargo doc --no-deps
```

### Step 5: Check Package


```bash
# Validate package before publishing

cargo package

# Check what will be published

cargo package --list
```

This creates a `.crate` file in `target/package/` and validates:
- ✅ All files are included
- ✅ `Cargo.toml` is valid
- ✅ No excluded files are present
- ✅ Package size is acceptable

### Step 6: Dry Run (Verify Package)


```bash
# Verify without publishing

cargo publish --dry-run
```

This will:
- ✅ Validate package structure
- ✅ Check `Cargo.toml`
- ✅ Verify file sizes
- ✅ Check for required files
- ✅ Show what will be published

**Expected Output:**
```
    Updating crates.io index
   Packaging WOWSQL v1.0.0 (/path/to/sdk/rust)
    Verifying WOWSQL v1.0.0 (/path/to/sdk/rust)
   Compiling WOWSQL v1.0.0 (/path/to/sdk/rust/target/package/WOWSQL-1.0.0)
    Finished dev [unoptimized + debuginfo] target(s) in 2.34s
   Uploading WOWSQL v1.0.0 (/path/to/sdk/rust)
```

### Step 7: Publish to crates.io


```bash
cargo publish
```

You'll see:
```
    Updating crates.io index
   Packaging WOWSQL v1.0.0 (/path/to/sdk/rust)
    Verifying WOWSQL v1.0.0 (/path/to/sdk/rust)
   Compiling WOWSQL v1.0.0 (/path/to/sdk/rust/target/package/WOWSQL-1.0.0)
    Finished dev [unoptimized + debuginfo] target(s) in 2.34s
   Uploading WOWSQL v1.0.0 (/path/to/sdk/rust)
    Uploaded WOWSQL v1.0.0 to registry
```

**Note**: Publishing is permanent! You cannot unpublish a version after 24 hours.

### Step 8: Verify Publication


Wait 5-10 minutes, then:

1. **Check crates.io:**
   - Visit: https://crates.io/crates/WOWSQL
   - You should see version 1.0.0!

2. **Check docs.rs:**
   - Visit: https://docs.rs/WOWSQL
   - Documentation should be available automatically

3. **Test Installation:**
   ```bash
   # Create test project

   cargo new test-WOWSQL

   cd test-WOWSQL

   
   # Add dependency

   # Edit Cargo.toml:

   [dependencies]

   WOWSQL = "1.0"

   
   # Build

   cargo build

   
   # Test import

   # Edit src/main.rs:

   use WOWSQL::WOWSQLClient;
   
   fn main() {
       println!("✅ WOWSQL Rust SDK imported successfully!");
   }

   
   cargo run

   ```

## 🐛 Troubleshooting


### Error: "cargo: command not found"


**Solution**: Install Rust:
```bash
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
```

### Error: "no token found"


**Solution**: Login to crates.io:
```bash
cargo login YOUR_TOKEN_HERE
```

Get token from: https://crates.io/me

### Error: "crate name 'WOWSQL' is already taken"


**Solution**: The crate name is already registered. Options:
1. Use a different name in `Cargo.toml`
2. Contact the owner of `WOWSQL` crate
3. Use a different name like `WOWSQL-sdk`

### Error: "crate already uploaded"


**Solution**: Version already exists. Increment version in `Cargo.toml`:
```toml
version = "1.0.1"  # or 1.1.0, 2.0.0
```

Then publish again.

### Error: "package size exceeds limit"


**Solution**: 
- Check `.cargoignore` excludes unnecessary files
- Remove large files from repository
- Maximum package size is 10MB

### Error: "failed to verify package tarball"


**Solution**: 
```bash
# Clean and rebuild

cargo clean
cargo package
```

### Error: "error calling dlltool 'dlltool.exe': program not found" (Windows)


This error occurs on Windows when using the GNU toolchain without MinGW/MSYS2 installed, or when dependencies need to link Windows libraries.

**Solution 1: Switch to MSVC Toolchain (Requires Visual Studio)**

The MSVC toolchain doesn't require `dlltool.exe`, but it requires Visual Studio Build Tools:

```powershell
# Check current toolchain

rustup show

# Install MSVC toolchain if not installed

rustup toolchain install stable-x86_64-pc-windows-msvc

# Set as default

rustup default stable-x86_64-pc-windows-msvc

# Verify

rustup show

# Try packaging again

cargo clean
cargo package
```

**⚠️ Important:** MSVC toolchain requires Visual Studio 2017+ or Build Tools for Visual Studio with C++ workload installed. If you get `link.exe not found` error, see the next troubleshooting section.

**Solution 2: Install MinGW/MSYS2 (Recommended for GNU Toolchain)**

This is the easiest solution if you're using the GNU toolchain:

1. **Download and Install MSYS2:**
   - Visit: https://www.msys2.org/
   - Download the installer (usually `msys2-x86_64-*.exe`)
   - Run the installer and follow the prompts
   - Default installation path: `C:\msys64`

2. **Open MSYS2 Terminal** (not PowerShell/CMD) and run:
   ```bash
   # Update package database

   pacman -Syu

   # (If prompted, close and reopen terminal, then run again)

   
   # Install MinGW toolchain

   pacman -S mingw-w64-x86_64-toolchain

   # Press Enter to accept default selection (all packages)

   ```

3. **Add MinGW to System PATH:**
   
   **Option A: Using PowerShell (Run as Administrator):**
   ```powershell
   # Add to user PATH (recommended)
   [Environment]::SetEnvironmentVariable(
       "Path",
       [Environment]::GetEnvironmentVariable("Path", "User") + ";C:\msys64\mingw64\bin",
       "User"
   )
   ```
   
   **Option B: Manual (Windows Settings):**
   - Press `Win + X` → System → Advanced system settings
   - Click "Environment Variables"
   - Under "User variables", select "Path" → Edit
   - Click "New" → Add: `C:\msys64\mingw64\bin`
   - Click OK on all dialogs

4. **Restart your terminal/PowerShell** (or restart your IDE)

5. **Verify dlltool is available:**
   ```powershell
   dlltool --version
   ```
   You should see version information.

6. **Try packaging again:**
   ```powershell
   cd sdk/rust
   cargo clean
   cargo package
   ```

**Solution 3: Skip Verification (Not Recommended)**

Only use this if you're certain the package is correct:

```powershell
# Package without verification (not recommended)

cargo package --no-verify
```

**Note:** `cargo publish` will still verify the package, so this only helps with `cargo package`.

### Error: "linker `link.exe` not found" (Windows MSVC)


This error occurs when using the MSVC toolchain without Visual Studio Build Tools installed.

**Solution 1: Install Visual Studio Build Tools (For MSVC Toolchain)**

1. **Download Build Tools:**
   - Visit: https://visualstudio.microsoft.com/downloads/
   - Scroll down to "Tools for Visual Studio"
   - Download "Build Tools for Visual Studio 2022"

2. **Install with C++ Workload:**
   - Run the installer
   - Select "Desktop development with C++" workload
   - Click "Install"
   - This installs `link.exe` and other MSVC tools

3. **Restart your terminal** and try again:
   ```powershell
   cargo clean
   cargo package
   ```

**Solution 2: Switch to GNU Toolchain (Easier Alternative)**

If you don't want to install Visual Studio Build Tools, use the GNU toolchain instead:

```powershell
# Switch to GNU toolchain

rustup default stable-x86_64-pc-windows-gnu

# Install MinGW/MSYS2 (see Solution 2 in dlltool error section)

# Then add to PATH and try again

cargo clean
cargo package
```

**Note:** The GNU toolchain is perfectly fine for Rust development on Windows and doesn't require Visual Studio.

### Error: "missing license field"


**Solution**: Add license to `Cargo.toml`:
```toml
license = "MIT"
```

### Error: "invalid characters in crate name"


**Solution**: Crate names must be lowercase alphanumeric with hyphens:
- ✅ `WOWSQL`
- ✅ `WOWSQL-sdk`
- ❌ `WOWSQL`
- ❌ `wow_mysql`

### Error: "documentation failed to build"


**Solution**: 
```bash
# Check docs locally

cargo doc --no-deps

# Fix any documentation errors

# Common issues:

# - Missing doc comments on public items

# - Invalid markdown in doc comments

# - Broken code examples

```
