# serde_clj

Convert Rust data structures to/from (relatively) idiomatic Clojure data
in memory using JNI.

See [test/src/lib.rs](test/src/lib.rs) for a usage example.

## Example

```rust
#[derive(Serialize)]
struct MyStruct {
    number: i32,
    names: Vec<String>
}
```
becomes
```clojure
{:number 3
 :names ["foo" "bar"]}
```

## Notes/TODO

* Unsigned integers serialize to the 'next biggest' type (except u64,
  which becomes i64), since Java doesn't really support unsigned.
* TODO: convert to/from BigInt where necessary.
* If you want to serialize a `Vec<u8>`, you should annotate or wrap
  the field with [serde_bytes](https://crates.io/crates/serde_bytes),
  or you will end up with a vector of `java.lang.Short`, which might
  not be what you wanted and isn't very efficient.
* More extensive tests.
