### Building a JSON-RPC Response in Ruby

Source: https://github.com/codingstones/jsonrpc/blob/master/README.md

Shows how to create a JsonRPC::Response object with a request ID and result value, and serialize it into a JSON string suitable for a JSON-RPC 2.0 response.

```Ruby
response = JsonRPC::Response.new(request_id: 'foo', result: 3)
response.to_json # {:jsonrpc=>"2.0", :id=>"foo", :result=>3}
```

### Parsing a JSON-RPC Request in Ruby

Source: https://github.com/codingstones/jsonrpc/blob/master/README.md

Demonstrates how to use the JsonRPC library to parse a JSON string representing a JSON-RPC 2.0 request and access its properties like version, params, id, and method. Requires a valid JSON-RPC formatted string as input.

```Ruby
require 'jsonrpc'

# First, we need a json with valid JSON-RPC format
p = {
    jsonrpc: '2.0',
    params: [1, 2],
    method: 'sum',
    id: 'foo'
}
request_body = JSON.generate(p)


# Let's parse it!
parser = JsonRPC::Parser.new
request = parser.parse(request_body)
request.invalid?  # false (validates the JSON-RPC format)
request.version   # 2.0
request.params    # [1, 2]
request.id        # 'foo'
request.method    # 'sum'
```
