-pub fn check_flag(flag: u16, in_: u16, not_in: u16) -> bool {
-    //! This function uses bitwise operations to test if flags are set or not.
-    //!
-    //! # Arguments
-    //!
-    //! * `flag`: u16 - The record flag you want to test
-    //! * `in_`: u16 - The flags you want to check if they are set (use 0 for no test)
-    //! * `not_in`: u16 - The flags you want to check if they are not set (use 0 for no test)
-    //!
-    //! # Usage:
-    //! example: let test if a flag is both paired and first in pair
-    //! ```
-    //! use rust_htslib::bam::flags::{Flag, check_flag};
-    //! let read_flag = 65;
-    //! assert_eq!(check_flag(read_flag, Flag::PAIRED + Flag::FIRST_IN_PAIR, 0), true);
-    //! ```
-    //! let test that the read is mapped. READ_UNMAPPED
-    //! ```
-    //! use rust_htslib::bam::flags::{Flag, check_flag};
-    //! let read_flag = 18;
-    //! assert_eq!(check_flag(read_flag, 0, Flag::READ_UNMAPPED), true);
-    //! ```
-    //!
-    //! Finally let do a more complexe real example test:
-    //! ```
-    //! use rust_htslib::bam::flags::{Flag, check_flag};
-    //! let read_flag = 19;
-    //! assert_eq!(check_flag(read_flag, Flag::PAIRED + Flag::PROPERLY_PAIRED + Flag::READ_RERVERSE , Flag::READ_UNMAPPED + Flag::MATE_UNMAPPED), true);
-    //! ```
-    //!
-    //binary flag check
-    //assert that: - in_ is in n
-    //             - not_in is not in n
-    // bitwise operation
-    if (not_in & flag) != 0 {
-        return false;
-    }
-    if (in_ & flag) != in_ {
-        return false;
-    }
-    return true;
