easy_paths

Convenience library for talented devs on tight schedules.

This library exists to streamline the data-type juggling normally associated with disk pathing by accepting generic strings ( str / String ) and returning String types.

Rust crate

Warnings

This library is tested on mac and linux.

This is completely untested on Windows.

Usage examples

All arguments can be of type 'str' or 'String'.

get_absolute_path

let string_path = "./test/test_b/test_c/../";
