Panic in multiple situations

[jackyzjk]

I have use nut to open three different boltdb config files which generate by Go language, I only read data with transaction, the code like this:

fn main() -> Result<(), Box<dyn std::error::Error>> {
        let db = DBBuilder::new("config.db").read_only(true).build()?;
        let tx = db.begin_tx()?;
        let b = tx.bucket(b"name")?;
        let Some(value) = b.get(b"key") else {return Err(Box::new(Error::new(ErrorKind::Other, "can't get key from bucket"))); };
        println!("{:?}", value);
        Ok(())
}

but there were several panic when I read different database file as follows:

• first

  thread 'main' panicked at 'unknown flag', /home/jicky/.cargo/registry/src/mirrors.sjtug.sjtu.edu.cn-be2141875385cea5/nut-0.1.1/src/consts/mod.rs:55:18
  stack backtrace:
  0:   0x4c1f14 - <unknown>
  1:   0x466c8c - <unknown>
  .....

• second

  thread 'main' panicked at 'range start index 36864 out of range for slice of length 32768', /home/jicky/.cargo/registry/src/mirrors.sjtug.sjtu.edu.cn-be2141875385cea5/nut-0.1.1/src/db/db.rs:731:59
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
  Aborted

Of course, I have also succeeded when I read the third database file.

It seems that in both cases db file is either corrupted or I missed something when porting. Did you try to open them with bolt db? Which version?

Second case should be fixed with new version. See #4
