Macro std::print1.0.0 [] [src]

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.

Use print! only for the primary output of your program. Use eprint! instead to print error and progress messages.


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


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

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


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