fix: bumped up tempfile to "3.26.0" The variables for --bytes, --ignore-initial and line count where size 'usize', thus limiting the readable bytes on 32-bit systems. GNU cmp is compiled with LFS (Large File Support) and allows i64 values. This is now all u64, which works also on 32-bit systems with Rust. There is no reason to implement a 32-bit barrier for 32 bit machines. Additionally the --bytes limit can be set to 'u128' using the feature "cmp_bytes_limit_128_bit". The performance impact would be negligible, as there only few calculations each time a full block is read from the file.

Fixed clippy warning. |
u64 seems the max file size with Rust, which is an Exabyte. Renamed type to Skip as this seems preferred.

feat: u64 for --bytes and --ignore-initial
fix: bumped up tempfile to "3.26.0"
The variables for --bytes, --ignore-initial and line count where size 'usize', thus limiting the readable bytes on 32-bit systems. GNU cmp is compiled with LFS (Large File Support) and allows i64 values.
This is now all u64, which works also on 32-bit systems with Rust. There is no reason to implement a 32-bit barrier for 32 bit machines.
Additionally the --bytes limit can be set to 'u128' using the feature "cmp_bytes_limit_128_bit".
The performance impact would be negligible, as there only few calculations each time a full block is read from the file.
This makes PR #172 obsolete.
