TOOL // OUTPUT DESTINATION
Rust Output Macro Chooser
Choose between print!, println!, eprint!, eprintln!, write!, writeln!, format!, and format_args! by destination and newline behavior.
01 // DESTINATION
Choose the job, not a macro nameWhere should the formatted output go?
02 // RECOMMENDATION
println!Use println! for a complete stdout line
println! writes formatted primary output to stdout and appends a newline.
Starting pattern
println!("value={value}");What this chooser decides
It selects among Rust's standard formatting and output macros based on destination and newline behavior. It does not inspect your program, benchmark I/O, or choose a formatting trait for the value itself.
