Hi
I have trouble to compile the following code:
import io::reader_util;
import vec::map;
fn main(args: [str]) {
let r = io::file_reader(args[1]); // r is result<reader, err_str>
if result::failure(r) {
fail result::get_err(r);
}
let rdr = result::get(r);
while !rdr.eof() {
let line = rdr.read_line();
io::println(line);
if str::len(line) != 0u {
let parts = vec::map(line.split_char(',')) {|s|
str::trim(s)
};
}
}
}
and got the errors:
$ rustc csv.rs <http://csv.rs>
csv.rs:17:33: 17:48 error: attempted access of field split_char on
type str, but no public field or method with that name was found
csv.rs:17 <http://csv.rs:17> let parts =
vec::map(line.split_char(',')) {|s|
^~~~~~~~~~~~~~~

What did I do wrong?
Hi Mic.
The available extension methods (as in `line.split_char(',')`) have been
changing a lot recently, so my guess is that your compiler is just
slightly out of date and doesn't have the `split_char` extension on
`str`. Try updating to Rust HEAD where you will also notice that
`result::failure` is now called `result::is_failure`.
