copy, delete, move and so on. It only operates on `Path Abs` which
guarantees us well-typed paths which are absolute.</p><p>Some functions are just path-safe wrappers around
unix functions, others have stricter exception handling
and some implement functionality that doesn't have a unix
counterpart (like <code>copyDirRecursive</code>).</p><p>Some of these operations are due to their nature not _atomic_, which
means they may do multiple syscalls which form one context. Some
of them also have to examine the filetypes explicitly before the
syscalls, so a reasonable decision can be made. That means
the result is undefined if another process changes that context
while the non-atomic operation is still happening. However, where
possible, as few syscalls as possible are used and the underlying
exception handling is kept.</p></div></div><div id="synopsis"><p id="control.syn" class="caption expander" onclick="toggleSection('syn')">Synopsis</p><ul id="section.syn" class="hide" onclick="toggleSection('syn')"><li class="src short"><span class="keyword">data</span> <a href="#t:FileOperation">FileOperation</a><ul class="subs"><li>= <a href="#v:FCopy">FCopy</a> <a href="HSFM-FileSystem-UtilTypes.html#t:Copy">Copy</a></li><li>| <a href="#v:FMove">FMove</a> <a href="HSFM-FileSystem-UtilTypes.html#t:Move">Move</a></li><li>| <a href="#v:FDelete">FDelete</a> [Path Abs]</li><li>| <a href="#v:FOpen">FOpen</a> (Path Abs)</li><li>| <a href="#v:FExecute">FExecute</a> (Path Abs) [<a href="https://hackage.haskell.org/package/bytestring-0.10.6.0/docs/Data-ByteString.html#t:ByteString">ByteString</a>]</li><li>| <a href="#v:None">None</a></li></ul></li><li class="src short"><span class="keyword">data</span> <a href="#t:Copy">Copy</a><ul class="subs"><li>= <a href="#v:PartialCopy">PartialCopy</a> [Path Abs]</li><li>| <a href="#v:Copy">Copy</a> [Path Abs] (Path Abs)</li></ul></li><li class="src short"><span class="keyword">data</span> <a href="#t:Move">Move</a><ul class="subs"><li>= <a href="#v:PartialMove">PartialMove</a> [Path Abs]</li><li>| <a href="#v:Move">Move</a> [Path Abs] (Path Abs)</li></ul></li><li class="src short"><span class="keyword">data</span> <a href="#t:FCollisonMode">FCollisonMode</a><ul class="subs"><li>= <a href="#v:Strict">Strict</a></li><li>| <a href="#v:Overwrite">Overwrite</a></li><li>| <a href="#v:OverwriteAll">OverwriteAll</a></li><li>| <a href="#v:Skip">Skip</a></li><li>| <a href="#v:Rename">Rename</a> (Path Fn)</li></ul></li></ul></div><div id="interface"><h1>Documentation</h1><div class="top"><p class="src"><span class="keyword">data</span> <a name="t:FileOperation" class="def">FileOperation</a> <a href="src/HSFM-FileSystem-UtilTypes.html#FileOperation" class="link">Source</a></p><div class="doc"><p>Data type describing file operations.
