## ✅ Next Steps
|
|
|
|
### To Run Benchmarks
|
|
|
|
1. **Ensure Rust is installed:**
|
|
```bash
|
|
rustup update stable
|
|
```
|
|
|
|
2. **Build the workspace:**
|
|
```bash
|
|
cargo build --release --all-features
|
|
```
|
|
|
|
3. **Run benchmarks:**
|
|
```bash
|
|
./scripts/run_benchmarks.sh
|
|
```
|
|
|
|
4. **View results:**
|
|
```bash
|
|
open target/criterion/SUMMARY.md
|
|
```
|
|
|
|
### For CI/CD Integration
