Thank you it correct my first problems.
I didn't send code because I thought it has the same cause. For the last
problems the code is :
use extra::serialize;
use extra::json::{Json, Decoder, ToJson, Object, Encoder, Decoder};
use extra::treemap::TreeMap;
use std::io::Decorator;
//second struct with manually implemented Decodable, Encodable
#[deriving(Decodable, Encodable, Eq)]
pub struct TestStruct2 {
dataInt: u8,
dataStr:~str,
dataArray:~[u8],
}
let test3 : TestStruct2 = TestStruct2 {dataInt: 1, dataStr:~"toto",
dataArray:~[2,3,4,5]};
//{\"dataArray\":[2,3,4,5],\"dataInt\":1,\"dataStr\":\"toto\"}
let mut m3 = MemWriter::new();
{
let mut encoder3 =Encoder::init(&mut m3 as &mut Writer);
test3.encode(&mut encoder3);
}
Rustc result :
test_json.rs:292:8: 292:36 error: type `TestStruct2` does not implement
any method in scope named `encode`
test/test_json.rs:292 test3.encode(&mut encoder3);

Le 05/12/2013 09:56, Kevin Ballard a écrit :
`do` no longer works with stack closures. It now only works with the new proc()
type, which basically means you're only going to see it used with spawn().
You need to now say something like
let rc = endpoint.with_c_str(|cstr| {
unsafe {smq_bind(self.sock, cstr)}
});
I can't speculate on your encode error without seeing it.

Hello,
since a few days, I have a lot of new errors in the master compiler. For
example in the rust_zmq lib that I use. When I compile it I have these errors :

I have the same type of errors in my code plus other error when the trait can't
be found like type `MyType` does not implement any method in scope named
`encode` and the function is implemented just above.
This code where compiling last week.
