Functions
void	fs::blocking::CreateDirectories (std::string_view path, boost::filesystem::perms perms)
	Create directory and all necessary parent elements. Condition when path already exists and is a directory treated as "success" and no exception is thrown.

void	fs::blocking::CreateDirectories (std::string_view path)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

void	fs::blocking::RewriteFileContents (utils::zstring_view path, std::string_view contents)
	Rewrite file contents synchronously.

void	fs::blocking::RewriteFileContentsFSync (utils::zstring_view path, std::string_view contents)
	Rewrite file contents synchronously and call `fsync`

void	fs::blocking::SyncDirectoryContents (utils::zstring_view path)
	flushes directory contents on disk using sync(2)

void	fs::blocking::Rename (utils::zstring_view source, utils::zstring_view destination)
	Renames existing file synchronously.

void	fs::blocking::RewriteFileContentsAtomically (utils::zstring_view path, std::string_view contents, boost::filesystem::perms perms)
	Rewrite file contents atomically.

void	fs::blocking::Chmod (utils::zstring_view path, boost::filesystem::perms perms)
	Change file mode synchronously.

bool	fs::blocking::RemoveSingleFile (utils::zstring_view path)
