some interesting topic about Rust on leetcode

use rustc source code to solve leetcode

leetcode-rust package require rustc_private feature to enable rustc relative API

e.g. use rustc_span::lev_distance::lev_distance(&a, &b) one line to solve leetcode edit-distance (Unfortunately we can't use nightly and rustc-dev in leetcode)

use rustc_graphviz visualize leetcode binary tree
