Surprises in the Rust JSON Ecosystem

• stdweb

  2 3,434 0.0 Rust

  A standard library for the client-side Web

But, I wish devs would atleast archive the repo and put a "NOT-MAINTAINED" notice in the readme. one of my surprises was stdweb crate with 150k+ downloads per month being dead for three years eg: https://github.com/koute/stdweb/issues/403

• roxmltree

  4 402 7.3 Rust

  Represent an XML document as a read-only tree.

In regards to the benchmarks, It makes sense to measure serializing/deserializing for parser crates. but since we are talking about dom implementations, metrics like traversal/iteration speed or insert/modification performance would be useful. a good example is roxmltree crate (readonly xml dom) which benches traversal/iteration performance and shows that by only focusing on readonly usecases, it gains substantial performance gains.

• InfluxDB

• hifijson

  1 12 3.1 Rust

  High-fidelity JSON lexer and parser

I have recently encountered similar problems as you and also created a JSON crate, hifijson. Its unique idea is that JSON parsing itself is not so hard, but JSON lexing is! Therefore, my crate provides a JSON lexer that you can use to create your custom JSON parser with any functionality you need. For example, this allows you to ignore escape sequences, giving you a &str for strings. Or, if you care about escape sequences, hifijson gives you a Cow similarly to serde_json, allocating new memory only if necessary.

• jaq

  24 2,497 9.6 Rust

  A jq clone focussed on correctness, speed, and simplicity

Just yesterday, I started work on replacing serde_json in my project jaq by hifijson, which cut JSON loading time in half! The downside of hifijson is that documentation is still TODO. But I intend to work on this as soon as I have a prototype of jaq with hifijson working.
