# Macro std::print 1.0.0[−][src]

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

Prints 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

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();
