Macro std::print

macro_rules! print {
    ($($arg:tt)*) => { ... };
}

Macro for printing to the standard output.

Equivalent to the println! macro except that a newline is not printed at the end of the message.

Note that stdout is frequently line-buffered by default so it may be necessary to use io::stdout().flush() to ensure the output is emitted immediately.

Panics

Panics if writing to io::stdout() fails.

Examples

use std::io::{self, Write};

print!("this ");
print!("will ");
print!("be ");
print!("on ");
print!("the ");
print!("same ");
print!("line ");

io::stdout().flush().unwrap();

print!("this string has a newline, why not choose println! instead?\n");

io::stdout().flush().unwrap();
