Implementation

fn writeHex(buf: []u8, x: usize) void {
    assert(std.mem.allEqual(u8, buf, '0'));
    const base = 16;
    var index: usize = buf.len;
    var a = x;
    while (a > 0) {
        const digit = a % base;
        index -= 1;
        buf[index] = std.fmt.digitToChar(@intCast(digit), .lower);
        a /= base;
    }
