Raw Blame History

This example explores 3 different ways you can create custom rejections for already existing extractors

  • with_rejection: Uses axum_extra::extract::WithRejection to transform one rejection into another
  • derive_from_request: Uses axum_macros::FromRequest to wrap another extractor and customize the rejection
  • custom_extractor: Manual implementation of FromRequest that wraps another extractor

cd examples && cargo run -p example-customize-extractor-error
