futures-enum

![crates-badge] ![docs-badge] ![license-badge] ![rustc-badge]

#[derive(Future, Stream, Sink, AsyncRead, AsyncWrite, AsyncSeek, AsyncBufRead)] for enums.

Usage

Add this to your Cargo.toml:

toml [dependencies] futures-enum = "0.1.13" futures = "0.3"

The current futures-enum requires Rust 1.36 or later.

Examples

```rust use futures_enum::*; use std::future::Future;

[derive(Future, Stream, Sink, AsyncRead, AsyncWrite, AsyncSeek, AsyncBufRead)]

enum Either { A(A), B(B), }

fn foo(x: i32) -> impl Future

{ if x < 0 { Either::A(async { 1 }) } else { Either::B(async move { x }) } } ```

futures-enum works well even if the dependency contains only sub-crates such as futures-core, futures-io, futures-sink, etc.

See auto_enums crate for how to automate patterns like this.
