## Introduction
The enum `Among` with variants `Left`, `Middle` and `Right` and trait implementations.
## Installation
- Use with default feature
```toml
[dependencies]
among = "0.1"
```
- Use without `std` and `alloc`
```toml
[dependencies]
among = { version = "0.1", default-features = false }
```
- Enable `futures` feature to enable trait implementation including `futures::io::AsyncRead`, `futures::io::AsyncBufRead`, `futures::io::AsyncWrite`, and `futures::io::AsyncSeek`.
```toml
[dependencies]
among = { version = "0.1", features = ["futures", "std"] }
```
- Enable `tokio` feature to enable trait implementation including `tokio::io::AsyncRead`, `tokio::io::AsyncBufRead`, `tokio::io::AsyncWrite` and `tokio::io::AsyncSeek`.
```toml
[dependencies]
among = { version = "0.1", features = ["tokio", "std"] }
```
