There is no easy way to navigate up the parse tree provided by jsoup selector syntax. We currently can navigate down very easily with Jsoup's selector syntax value.parseHtml().select("div > p") and also value.parseHtml().select("div:has(@) ~ div") but
this does not directly allow DOM traversal itself. However, Jsoup conveniently provides DOM traversal for finding a https://jsoup.org/apidoc

steps to reproduce

Write a loop, from 1 to 80000, each time add a random int to the max heap.

In theory it takes very little time(NlogN, N=80000, <1sec ), but the program does take a long time.

I'v also tested the BinaryHeap in https://github.com/SolutionsDesign/Algorithmia, it performs well, so it is probably due to the bad algorithm.

In the following file we have already ported some tests from Go to Rust:
https://github.com/crossbeam-rs/crossbeam-channel/blob/master/tests/golang.rs

The idea is to blindly port all the tests for Go channels line by line, which will give us additional confidence in the correctness of crossbeam-channel.

In the test file, you can find stubs with links to the original tests written in Go and
