serde-feature-hack 0.2.1

# serde-feature-hack

**DEPRECATED**: Since Rust 1.31 it's possible to
[rename dependencies](https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#renaming-dependencies-in-cargotoml).
There is no need to use this crate anymore.

A hack to allow having a feature named `serde` which doesn't just depend on serde

In Cargo.toml, you can do the following:

```toml
[dependencies]
serde-feature-hack = { version = "0.1.0", optional = true }

[features]
serde = ["serde-feature-hack", "some-other-dependency"]
```

Then, you can use `serde` like you normally would, except the crate name is
`serde_feature_hack`. It's possible to import it with the usual `serde` name.

```rust
extern crate serde_feature_hack as serde;
extern crate serde_json;

use serde::{Serialize, Serializer};

struct X;

impl Serialize for X {
    fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error> {
        serializer.serialize_str("Hello, world!")
    }
}

assert_eq!(serde_json::to_string(&X).unwrap(), r#""Hello, world!""#);
```
