Hi!
I’m trying to build libstd like separate library (long term goal is Rust +
libstd in kernel drivers). So, I made a copy of lib std and compiling it:
num/int_macros.rs:231:1: 231:19 error: failed to find an implementation of
trait kinds::Copy for int
num/int_macros.rs:231 impl Int for $T
Best regards,
Alexander

Fixed. —cfg stage0 should be used.

Brian, thank you for explanation. But, in that case I have one more
question. If PipeBytePort is unsendable any more, how bidirectional,
pipe_stream
based communication could be organised?

, but I'd like to learn, and I'd like to help when I can.
According to the tutorial, both chan and port should be sendable types
that can be transferred to the task's closure.
I'm interested in what's going on here as well.

Hi!
As I know, As I know, we have SharedChan mechanism which can be used for
many clients - server communications. But how can I send response from
server to many clients? This is not commonly used case, and looks like
there is no such mechanism or I've missed something?
Best regards,
Alexander.
Hi all, I'm really confused. What's about Shared 2 Owned conversions? This
one looks ugly, nevertheless works:
let a = @5;
let b = *a;
let c = ~b;
io::println(fmt!(%?, %?, %?, a, b, c));
@5, 5, ~5
But what about arrays?
let a = @[5];
let b = *a;
let c = ~b;
error: type @[VI0] cannot
Second response not about deep copy but about simplifying deep copy
operation. Actually, I understood the reason of deep-copy-only
conversions immediately after sending the question. And big source code
overhead from nothing means: we almost always have to write conversion
manually rather than do
I'm trying to understand the idea of DuplexStream. First of all, it can't be
used for cross-task communications:
13 let value = gen_data();
14 let (server, client) = DuplexStream();
15
16 do task::spawn {
17 let val: ~[uint] = server.recv();
18
Do we have any possibility to do something like this or only owned values
can be send?
11 fn task_with_shared_pointers() {
12 let value = @[1, 2, 3, 4, 5];
13 let (server_chan, server_port) = stream();
14
15 do task::spawn {
16 let val: @[uint] = server_chan.recv();
I always thought that it is possible to write next code:
let box_box = ~[1 .. 5];
And obtain the vector with [1, 2, 3, 4, 5], but it doesn't works. What is
the simplest way to do it?

I'm not sure it is an defect or failure to fully understand from my side. I'd

Have we a pretty looks solution for auto incrementation counters during loops?
I mean something like C/C++ style for loop.I found an example in the manual

way for solving problem?
Thanks.
I guess, the solution will not work for -1 … -10

I'm trying to convert tuple of uints to string using to_str() module like
this:
io::println((1,2).to_string());
Looks like it should work as to_str has implementation for (A, B), but:

Yes, you're right, just typo.Thanks!

Hi Alexander
Looks like a typo. The function your code calls is to_string() instead of
to_str(). Tried the statements below and both worked:
io::println(fmt!(%s, (1,2).to_str()));
I want to add function like _1(), _2(), etc for Rust tuple. Unfortunately I
do not understand how to tell compiler lifetime of returning result in case
of `trait`
pub trait TupleValT {
pub pure fn _1() - T;
pub pure fn _2() - T;
}
impl T(T, T): TupleValT {
pure fn _1() - T {
I've found mentions of Reflection system in Doc detailed release notes,
unfortunatly the explanation is totally unclear for me. After that, I found

Can someone give a good enough explanation of 'copy' keyword usage? I can't

Am I right that this information is type of memory leak report? If it is true,
is it possible to find time of memory allocation?

Unfortunately, I didn't caught your idea with with_fixture :( I have next
situation, may be you have an idea how to fix it:
I need to allocate unique TCP ports numbers for each test. In case of C/C++
solution is extreamly easy: create singleton or static variable and just

I suppose that singleton tasks is the only way in this case. At least
because of current testing facilities are usefull just for unit testing,
but not for complex module testing, and in case of complex test cases we
need to share some information between components. Also it will be needed

I have a type which will be bind to appropriate C structure:

How could I get size of the test_type? How could I provide an information about
