Among

The enum Among with variants Left, Middle and Right is a general purpose sum type with three cases.

LoC

The enum Among with variants Left, Middle and Right and trait implementations.

Use without std and alloc

[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.
```
[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.
```
[dependencies]
among = { version = "0.1", features = ["tokio", "std"] }
