Performance

Negative values mean that the library failed the test.

The tests are done on my PC. The following libraries are tested:

  • typedload, the 3 most recent versions. It shines with tagged unions, which is what I mostly use.
  • pydantic2 years of work to rewrite it in Rust, implemented detection of tagged unions years after I did it, still managing to lose some benchmarks 😅
  • apischema is slower where there are unions, faster otherwise
