how to convert a binary number into a string

Question

Would anyone know how to convert a binary number into a string that represents its digits ?

let  s: u32 = 0b00100000001011001100001101110001110000110010110011100000;

I need study different parts of this binary number by cuting it into pieces (ex first 5 digits, then digit 6 to 15, etc...).

In order to do so, I'm thinking using string slices but first I need to convert the binary number into a string ( "00100000010110011...").

Thank you !

First 5 binary digits: `s & 0x1F`, digits 6 to 15: `(s >> 6) & 0x3FF` — Jmb, Feb 10 '22 at 14:44

Use binary format:

fn main() {
    let s: u64 = 0b00100000001011001100001101110001110000110010110011100000u64;
    let s_str: String = format!("{s:b}");
    println!("{s_str}");
}
