#### std::fs alternatives
|
||||
|
||||
- [ ] `std::fs::canonicalize` - `path(path).canonicalize()` - Returns the canonical, absolute form of a path with all intermediate components normalized and symbolic links resolved.
|
||||
- [x] `std::fs::canonicalize` - `path(path).canonicalize()` - Returns the canonical, absolute form of a path with all intermediate components normalized and symbolic links resolved.
|
||||
- [x] `std::fs::copy` - `file(path).copy(target)` - Copies the contents of one file to another. This function will also copy the permission bits of the original file to the destination file.
|
||||
- [x] `std::fs::create_dir` - `dir(path).create()` - Creates a new, empty directory at the provided path
|
||||
- [x] `std::fs::create_dir_all` - `dir(path).create_all()` - Recursively create a directory and all of its parent components if they are missing.
