Hi,
I don't know how to figure out calling by_ref() for a PipeStream:
use std::io::Process;
use std::io::BufferedReader;
fn main() {
let mut child = match Process::new("/usr/bin/xzcat",
["test.log.xz".to_owned()]) {
Ok(child) => child,
Err(e) => fail!("failed to execute child: {}", e),
};
let inp = child.stdout.get_mut_ref();
// ERROR occurs here
let mut rdr = BufferedReader::new(inp.by_ref());
for line in rdr.lines() {
print!("{}", line.unwrap());
}
assert!(child.wait().success());
}
This is the error output:
test.rs:13:37: 13:49 error: multiple applicable methods in scope
test.rs:13 let mut rdr = BufferedReader::new(inp.by_ref());
^~~~~~~~~~~~
test.rs:13:37: 13:49 note: candidate #1 is `std::io::Writer::by_ref`
test.rs:13 let mut rdr = BufferedReader::new(inp.by_ref());
^~~~~~~~~~~~
test.rs:13:37: 13:49 note: candidate #2 is `std::io::Reader::by_ref`
test.rs:13 let mut rdr = BufferedReader::new(inp.by_ref());
^~~~~~~~~~~~
test.rs:13:17: 13:36 error: failed to find an implementation of trait
std::io::Reader for std::io::RefWriter<,std::io::pipe::PipeStream>
test.rs:13 let mut rdr = BufferedReader::new(inp.by_ref());
^~~~~~~~~~~~~~~~~~~
Any hints?
Actually what I want to accomplish is to iterate line by line over a
PipeStream.
Regards,
Michael
