Minimal recursive "truncate file/directory names to meet requirements" tool

Overview

trunc_filenames

ssokolow@monolith ~ % trunc_filenames --help
trunc_filenames 0.1.0
Rename files and directories to fit length limits.

WARNING: Will not preserve secondary extensions like .tar.gz

USAGE:
    trunc_filenames [OPTIONS] [PATH]...

ARGS:
    <PATH>...    Paths to rename (recursively, if directories)

OPTIONS:
    -h, --help                 Print help information
        --max-len <MAX_LEN>    Length to truncate to. (Default chosen for rclone name encryption)
                              [default: 140]
    -n, --dry-run              Don't actually rename files. Just print
    -V, --version              Print version information

Current shortcomings

  1. Requires a POSIX platform because I didn't want to do something hacky and then forget, so I only bothered to implement "the length we care about is the encoded length" based on std::os::unix::ffi::OsStrExt.
  2. Doesn't preserve secondary extensions like the .tar in .tar.gz
  3. If the file/directory name already contains bytes that aren't valid UTF-8, it won't bother to ensure that the truncation falls on the boundary between valid UTF-8 code points.

All of these are because it was a quick itch-scratch I would normally write in Python and not even revision-control or upload, it works well enough for the problem it was meant to solve, and solving any of those would have a significantly lower return on investment.
