std::print! [] [src]

macro_rules! print {
    ($($arg:tt)*) => ($crate::io::_print(format_args!($($arg)*)));
}

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.

Examples

fn main() { 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(); }
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();
