printstd() does not lock stdout

[yongqli]

The program below produces garbled output:

main.rs:

use prettytable::{Table, format, cell, row};

fn print_table(s: usize) {
    let mut table = Table::new();
    table.set_titles(row![c => "num"]);
    table.set_format(*format::consts::FORMAT_NO_LINESEP_WITH_TITLE);
    for i in s..s+100 {
        table.add_row(row![i]);
    }
    table.printstd();
}

fn main() {
    rayon::join(|| print_table(0), || print_table(1000));
}

Cargo.toml:

[package]
name = "prettytabletest"
version = "0.1.0"
edition = "2018"

[dependencies]
prettytable-rs = "*"
rayon = "1.0"

Same issue here, when I pipe to less, or `more

Any update here?

I have found a workaround: you can lock stdout before calling printstd() because the lock is reentrant in practice, although it is not documented. I created an extension method printstdlocked(&self) which calls std::io::stdout().lock() before calling self.printstd();
