I'm having difficulty compiling even the first sample. Nothing I do can
convince my rust 0.7 compiler of the existence of flatpipes... but I'm new
to this whole thing anyways.
The one thing that jumps out at me: should the second example have "||"
after the word 'spawn' in the do statement? i.e. do task::spawn || {
instead of do task::spawn {
My understanding is that the empty vertical bars indicate an empty argument
name list, so it should have no negative effect on the code, but it's worth
testing, I suppose. What "use" or "extern mod" statements did you place at
the top of the Rust files in order to get them to compile? I may not know
much, 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.
