From https://arrow.apache.org/faq/ :

> How does Arrow relate to Flatbuffers?

> Flatbuffers is a low-level building block for binary data serialization. It is not adapted to the representation of large, structured, homogenous data, and does not sit at the right abstraction layer for data analysis tasks.

> Arrow is a data layer aimed directly at the needs of data analysis, providing a comprehensive collection of data types required to analytics, built-in support for “null” values (representing missing data), and an expanding toolbox of I/O and computing facilities.

> The Arrow file format does use Flatbuffers under the hood to serialize schemas and other metadata needed to implement the Arrow binary IPC protocol, but the Arrow data format uses its own representation for optimal access and computation

Nice that comfy gets even easier. Also, if serde's compile time is an issue, then there's nanoserde which is usually much much faster according to benchmarks

A note on performance and size: Some benchmarks and statistics are included in the README. But only because people will be curious. I've based my methodology on rust_serialization_benchmark, but decided to not extend it (for now) since it seems to exclude any Rust types which are not widely supported by all formats being tested (like HashMap's and 128-bit numbers). The test suite is already quite nice if you want to take it for a spin.

While we haven't benchmarked either of those ourselves. You can checkout rust_serialization_benchmark which has protobuf under the name prost.

Update: Benchmark PR submitted: https://github.com/djkoloski/rust_serialization_benchmark/pull/37

Here is a speed and size benchmark of different rust binary serialization formats: https://github.com/djkoloski/rust_serialization_benchmark Warning: I think the creator of this benchmark is also the creator of rkyv, one of the best positioned formats in the benchmark.

So I assume you're deserializing them before processing the book? If so then if you want an easy speed-up you could also take a look at these benchmarks and pick a faster serialization crate. (: (Although you might or might not get a big speedup; depends on what exactly you're deserializing and how much you are deserializing.)

You can add the rust serialization benchmark to that list

Hey! Similar to bincode, it provides a very similar, compact binary format. The rkyv benchmark is the most comprehensive I'm aware of, but compared to bincode, postcard is generally a similar speed for serialization or deserialization (maybe a touch slower), but generally produces a slightly smaller "on the wire" size.

You should add your crate to these benchmarks. (Which are, AFAIK, the most comprehensive set of benchmarks currently available for Rust serialization libraries.)

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).
