## Dependencies
This crate is built on:
- the [Pest parser](https://crates.io/crates/pest) crate
- [tokio](https://crates.io/crates/tokio), [tokio-util](https://crates.io/crates/tokio-util) and [tokio-stream](https://crates.io/crates/tokio-stream) for the async features
- mixed encoding detection and conversion is achieved through [chardetng](https://crates.io/crates/chardetng) and [encoding_rs](https://crates.io/crates/encoding_rs)
- [tokio](https://crates.io/crates/tokio), [tokio-util](https://crates.io/crates/tokio-util) and [futures-util](https://crates.io/crates/futures-util) for the async features
