Crate path_slash

A library for converting file paths from/to slash paths

A slash path is a path whose components are separated by separator '/' always.

In Unix-like OS, path separator is slash '/' by default. So any conversion is not necessary. But on Windows, file path separator '' needs to be replaced with slash '/' (and of course '' for escaping character should not be replaced).

For example, a file path 'foo\bar\piyo.txt' can be converted to/from a slash path 'foo/bar/piyo.txt'

This package was inspired by Go's path/filepath.FromSlash and path/filepath.ToSlash.
