argparse-benchmarks-rs VS template-benchmarks-rs

You can check out the argparse-benchmarks-rs though that only gives a high level summary.

So besides the git2 conversation, I'd recommend using an argument parser even if its for something basic like lexopt just for help/version, at least you'd error for unrecognized arguments and can more easily expand it in the future.

Unclear whether it has a solid advantage over other things listed at rust-cli/argparse-benchmarks-rs or whether it's just an "I didn't research what already existed" project.

I'm tempted to collect all of these benchmark repos into a github org to make them easier to find. So far I know of parser, md, argparse, and template languages.

Not strictly an answer to your question, but https://github.com/rust-cli/argparse-benchmarks-rs provides a good survey of option parsing crates in Rust.

As others have mentioned clap is one of the more popular, featureful CLI parsers though it does come at a compile time and binary size cost. We are working on improving that. See argparse-benchmarks for by-the-numbers comparison for the different parsers (ie only stats and no full feature lists). Clap is used by ripgrep, cargo, and many other tools

Compared to lexopt, which inspired this effort, clap_lex makes some different trade offs for flexibility and ergonomics which allows it to handle every case clap needs. There is room for more ergonomic improvements as the MVP was written for clap's needs. argparse-benchmarks-rs has been updated and clap_lex is roughly in line with lexopt for build-times and binary size.

btw there are the argparse benchmarks which can be interesting points of comparison (though I haven't decided what is the criteria for being added to it yet).

Any recommendations for rust template engines? I'd like something that can easily render labeled fragments of a template instead of requiring me to split a page into a dozen little files. Kinda like inline {{block}} definitions in Go's html/template. Speed is also nice.

From template-benchmark-rs [0] I found sailfish [1] (fast, but no fragments(?)). render-rs [2] and syn-rsx [3] (2022) both let you write html in rust macros which is cool (maybe that can substitute for fragments?). Then there's gtmpl-rust [4] which is just Go templates reimplemented in rust.

Personally, I'd recommend Maud if you don't need something with runtime reloading. Not only is it much faster, it implements a template language that is effectively the Rust-syntax equivalent to Slim or Haml using a procedural macro, so you get compile-time verification that your HTML output is well-formed.

I've been maintaining several benchmark repos based off of template-benchmarks-rs. I've noticed there are several other benchmark repos that are hard to know about.

I'm tempted to collect all of these benchmark repos into a github org to make them easier to find. So far I know of parser, md, argparse, and template languages.

Simple and straightforward. The only thing I'd change personally is using sailfish over markup. Seems to be the fastest templating engine?

As I said in my other post, runtime performance wasn't a concern for me except to catch anything egregious, like mini_markdown hanging. If people want to expand on this with different representative cases and criterion like template-benchmarks-rs, they are welcome to!

That's why I use Sailfish for server-side templating in my Rust web projects. It's ridiculously fast.

As for templating, here's a benchmark that can double as a list of candidates to choose from... though, again, Rust stuff tends to be fast, so don't assume that the slowest templating engine on a Rust-vs-Rust benchmark is going to be slow.

Yeah. You're much better off worrying about template rendering performance or database query optimization than the framework itself.
