Rgb to hex conversion

// rgb to hex conversion
fn rgb(r: i32, g: i32, b: i32) -> String {
    format!("{:02X}{:02X}{:02X}", 
        r as f32 as u8, 
        g as f32 as u8, 
        b as f32 as u8) 
}

fn main() {
    let (r, g, b) = (123, 86, 200);
    println!("rgb {} {} {} to hex {} ", r, g, b, rgb(r, g, b));
}

Hex to rgb function

function hex2RGB(hex){
        const r = parseInt(hex.substring(1, 3), 16);
        const g = parseInt(hex.substring(3, 5), 16);
        const b = parseInt(hex.substring(5, 7), 16);
        return `${r}, ${g}, ${b}`;
}

Convert RGB To Hex

const rgbToHex = (r, g, b) =>
  "#" + ((1 << 24) + (r << 16) + (g << 8) + b).toString(16).slice(1);

rgbToHex(0, 51, 255); 
// Result: #0033ff
