rust - Printing a character a variable number of times with println -

i want use println! , powerful formatting tools of format! print character specific number of times. of course possible loop, so:

fn give_love(count: usize) {     print!("here love you: ");     in 0..count {         print!("♥");     }     println!(""); } 

but neither want write loop nor 3 prints. how shorter/better?

solution code

fn give_love(count: usize) {     println!("here love you: {:♥<1$}", "", count); } 

---

explanation

you can (mis-)use fill feature allows fill printed value character of choice. grammar feature alone looks like:

'{' ':' <fill> <align> <width> '}' 

where width either constant number or reference argument of type <argument_index> '$'. 3 mean width of constant 3 , 1$ mean width of value of 1st argument of println!.

---

however: here kind of "misusing" feature , mustn't forget specifying "fill" other printable thing, passed argument println. can empty string though.

println!("love: {:♥<3}", "");     // love: ♥♥♥ println!("love: {:♥<1$}", "", 5); // love: ♥♥♥♥♥ 

here examples don't pass empty string:

println!("love: {:♥<5}", "#");    // love: #♥♥♥♥ println!("love: {:♥>5}", "#");    // love: ♥♥♥♥# println!("love: {:♥^5}", "#");    // love: ♥♥#♥♥
