Building error

[sylvainpelissier]

I have the following error while building the project:

$ cargo build
   Compiling luks2 v0.5.0 (/home/user/luks2)
error[E0599]: no method named `skip_fixed_array_length` found for struct `Configuration` in the current scope
   --> src/lib.rs:101:93
    |
101 |         let options = bincode::config::legacy().with_big_endian().with_fixed_int_encoding().skip_fixed_array_length();
    |                                                                                             ^^^^^^^^^^^^^^^^^^^^^^^ method not found in `Configuration<BigEndian, Fixint>`

For more information about this error, try `rustc --explain E0599`.
