Module backend 

Abstract big integer backend. This module makes no guarantees of applicability, all methods are considered internal, except for conversion functions:

• Integer::to_bytes_lsf
• Integer::to_bytes_msf
• Integer::from_bytes_msf
• Integer::to_str_radix
• Integer::from_str_radix
• num_bigint::Integer::to_num_bigint
• num_bigint::Integer::from_num_bigint
• rug::Integer::to_rug
• rug::Integer::from_rug

Likewise, the serde serialization format is also well-defined and stable, even compatible with older versions of this library.

To select a backend, use a feature flag:

• backend-num-bigint (default) - use num-bigit
• backend-rug - use rug

When both features are enabled at once, num-bigint is used
