Rust JSONRPC 1.0 Client

Rudimentary support for sending JSONRPC 1.0 requests and receiving responses.

This library is based on rust-jsonrpc.

Serde Support

This includes a of macro to enable serialization/deserialization of structures without using stable or nightly. They can be used as follows: ```rust

[macro_use] extern crate jsonrpc;

extern crate serde;

struct MyStruct { elem1: bool, elem2: String, elem3: Vec } serdestructimpl!(MyStruct, elem1, elem2, elem3 <- "alternate name for elem3"); ``` When encoding, the field will be given its alternate name if one is present. Otherwise the ordinary name is used.

There is also a variant of this for enums representing structures that might have one of a few possible forms. For example ```rust struct Variant1 { success: bool, success_message: String }

struct Variant2 { success: bool, errors: Vec }

enum Reply { Good(Variant1), Bad(Variant2) } serdestructenumimpl!(Reply, Good, Variant1, success, successmessage; Bad, Variant2, success, errors ); ``` Note that this macro works by returning the first variant for which all fields are present. This means that if one variant is a superset of another, the larger one should be given first to the macro to prevent the smaller from always being matched.

JSONRPC

To send a request which should retrieve the above structure, consider the following example code

```rust

[macro_use] extern crate jsonrpc;

extern crate serde;

struct MyStruct { elem1: bool, elem2: String, elem3: Vec }

serdestructimpl!(MyStruct, elem1, elem2, elem3);

fn main() { // The two Nones are for user/pass for authentication let mut client = jsonrpc::client::Client::new("example.org", None, None); let request = client.buildrequest("getmystruct", vec![]); match client.sendrequest(&request).andthen(|res| res.intoresult::()) { Ok(mystruct) => // Ok! Err(e) => // Not so much. } }

```
