The write_function
will be called repeatedly as data is received over the wire. In your example, you are feeding a partial JSON blob to serde_json which will fail since it hasn't received the entire output. Depending on what you need to do, you'll either need to buffer the results in memory, or stream them to some other place (like a file, stdout, etc.). The write_function
docs go into more detail.

Thanks, @ehuss
You was right about it. My mistake!
Just in case someone has the same problem a leave my solution for this problem:
fn main() {
let buf = RefCell::new(Vec::new());
let mut handle = Easy::new();
handle.url("https://start.spring.io").unwrap();
handle.accept_encoding("application/json").unwrap();
let mut transfer = handle.transfer();
transfer.write_function(|data| {
buf.borrow_mut().extend_from_slice(data);
Ok(data.len())
}).unwrap();
transfer.perform().unwrap();
let borrowed = buf.borrow();
let value: Value = serde_json::from_slice(borrowed.as_slice()).unwrap();
println!("{:?}", value);
}
Thanks!
