Soni's Serde Utilities
======================

This crate provides some utilities for use with serde.

Currently, it provides `MayBe<T>`, a deserializable that doesn't error if
something doesn't match a `T`. For example, it enables the JSON:

```json
{
  "bar": []
}
```

to successfully deserialize into the Rust struct:

```rust
#[derive(Deserialize)]
struct Foo {
  bar: MayBe<f64>,
}
```

as a `foo.bar.is_not()`.
