Provides injectable Filesystem and Network resources to make code more testable.
### FileSystem
There are two FileSystem implementation: [filesystem] and [fs].
- [filesystem] is the legacy implementation and will be removed in a future version.
- [fs] is the current version and is intended to stand-in for and extend the [std::fs] module from the Standard Library.
#### std::fs alternatives
| To Do | [std::fs] | [kxio::fs] | |
| ----- | ---------------- | --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------ |
| [ ] | canonicalize | path::canonicalize | Returns the canonical, absolute form of a path with all intermediate components normalized and symbolic links resolved. |
| [ ] | copy | file::copy | Copies the contents of one file to another. This function will also copy the permission bits of the original file to the destination file. |
| [ ] | create_dir | dir::create | Creates a new, empty directory at the provided path |
| [ ] | create_dir_all | dir::create_all | Recursively create a directory and all of its parent components if they are missing. |
| [ ] | hard_link | link::create | Creates a new hard link on the filesystem. |
| [ ] | metadata | path::metadata | Given a path, query the file system to get information about a file, directory, etc. |
| [ ] | read | file::read | Read the entire contents of a file into a bytes vector. |
| [ ] | read_dir | dir::read | Returns an iterator over the entries within a directory. |
| [ ] | read_link | link::read | Reads a symbolic link, returning the file that the link points to. |
| [ ] | read_to_string | file::read_to_string | Read the entire contents of a file into a string. |
| [ ] | remove_dir | dir::remove | Removes an empty directory. |
| [ ] | remove_dir_all | dir::remove_all | Removes a directory at this path, after removing all its contents. Use carefully! |
| [ ] | remove_file | file::remove | Removes a file from the filesystem. |
| [ ] | rename | path::rename | Rename a file or directory to a new name, replacing the original file if to already exists. |
| [ ] | set_permissions | path::set_permissions | Changes the permissions found on a file or a directory. |
| [ ] | symlink_metadata | link::metadata | Query the metadata about a file without following symlinks. |
| [ ] | write | file::write | Write a slice as the entire contents of a file. |
| [ ] | try_exists | path::exists | Returns Ok(true) if the path points at an existing entity. |
### Network
The entire [network] module needs to be completly rewritten
It's use is strongly discouraged.
A new [net] module will likely be its replacement.
