# TDengine driver connector for Rust
It's a rust implementation for [TDengine](https://github.com/taosdata/TDengine), an open-sourced big data platform designed and optimized for the Internet of Things (IoT), Connected Cars, Industrial IoT, and IT Infrastructure and Application Monitoring.
## Dependencies
- Rust:
```
curl https://sh.rustup.rs -sSf | sh
```
## Run with Sample
Build and run basic sample:
```
cargo run --example demo
```
Build and run subscribe sample:
```
cargo run --example subscribe
```
// build.rs
