| 100% Rust |
| Powered by the Rayon library for high parallel perfomance |
| Supported on Unix-based platforms |
| Extremely fast at synchronizing directories with large quantities of files |
| Multithreaded copy, remove, and sync |
| A progress bar using indicatif |
USAGE:
lms [SUBCOMMAND]
FLAGS:
-h, --help Prints help information

-n, --nodelete Do not delete any destination files
-s, --secure Use a cryptographic hash function for hashing similar files
-S, --sequential Copy files sequentially instead of in parallel
-V, --version Prints version information
-v, --verbose Verbose outputs

<TARGET> Target directoryUsing hyperfine on an Intel i7-8550U with the following 2 test folders,
| Directory | Directory Size | Number of Files |
|---|---|---|
| 1 | 88MB | 7262 |
| 2 | 105MB | 252 |
| Command | Directory | Time |
|---|---|---|
| lms sync | 1 | 179.1 ms ± 5.1 ms |

Of course, these benchmarks can be highly dependent on CPU and IO devices.
