Benchmark Rust libraries working with HTML:
|
|
- [`scraper`](https://crates.io/crates/scraper) (built with [`html5ever`](https://crates.io/crates/html5ever))
|
|
- [`tl`](https://crates.io/crates/tl)
|
|
- *(haven't found anything else that can build DOM, select an element and serialize)*
|
|
|
|
Output is unformatted CSV (probably because I'm lazy),
|
|
a nushell's `from csv` can be used to print a neat table.
|
|
|
|
Test results on my PC:
|
|
```
|
|
~/code/html-rs-bench> cargo run -r | save -f result; open result | from csv
|
|
Finished `release` profile [optimized] target(s) in 0.03s
|
|
Running `target/release/html-rs-bench`

Keep in mind that, despite `tl` being really fast (except serializing many tags in `tochb` sample),
|
|
it's not a browser-grade parser, and also that it doesn't fully support the CSS selector syntax
|
|
(e.g. `a[data-abc]` is OK, but not `a[data-abc="123"]`).
|
|
|
|
I do not own anything in the sample HTML pages. Here are the sources:
|
|
- `tochb` - [Dictionary of Tocharian B](https://www.win.tue.nl/~aeb/natlang/ie/tochB.html)
|
|
- `android` - [BluetoothDevice Android API reference](https://developer.android.com/reference/android/bluetooth/BluetoothDevice)
|
|
- `10mb` - [Random 10MB page with Shakespeare's poem](https://github.com/adriancbjie/my-kitty-cat/raw/master/web/staticpages/10MB.html)
|
|
|
|
Size of developer.android.com is surprising...
|
|
It's ~3.8 MiB even for the API reference homepage.
|
|
It's bigger than the whole Tocharian-B dictionary.
