Hi,
I am getting the following errors:
$ rustc csv_create.rs
csv_create.rs:17:1: 17:14 error: attempted access of field write_str on
type core::io::writer, but no public field or method with that name was
found
csv_create.rs:17 rdr.write_str("aaa, bbb,ccc ,
ddd,eee,fff,ggg,hhh,iii,jjj,kkk,lll,mmm,nnn\n");
^~~~~~~~~~~~~
csv_create.rs:17:1: 17:78 error: mismatched types: expected function or
native function but found _|_
csv_create.rs:17 rdr.write_str("aaa, bbb,ccc ,
ddd,eee,fff,ggg,hhh,iii,jjj,kkk,lll,mmm,nnn\n");
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
with the following code:
import io::reader_util;
import vec::map;
fn main(args: [str]) {
let r = io::file_writer("csv.csv" , [io::create, io::truncate]); // r
is result<reader, err_str>
if result::is_failure(r) {
fail result::get_err(r);
}
let rdr = result::get(r);
let count = 0;
while true {
if count == 4000000 { break; }
rdr.write_str("aaa, bbb,ccc ,
ddd,eee,fff,ggg,hhh,iii,jjj,kkk,lll,mmm,nnn\n");
count += 1;
}
}
What did I do wrong and would it possible to rewrite the while loop with
for loop?
Thank you in advance.
