axum-core - v0.2.0

on GitHub

added: Add IntoResponseParts trait which allows defining custom response
types for adding headers or extensions to responses (#797)

breaking: Using HeaderMap as an extractor will no longer remove the headers and thus
they'll still be accessible to other extractors, such as axum::extract::Json. Instead
HeaderMap will clone the headers. You should prefer to use TypedHeader to extract only the
headers you need (#698)

This includes these breaking changes:

• RequestParts::take_headers has been removed.
• RequestParts::headers returns &HeaderMap.
• RequestParts::headers_mut returns &mut HeaderMap.
• HeadersAlreadyExtracted has been removed.
• The HeadersAlreadyExtracted variant has been removed from these rejections:
  • RequestAlreadyExtracted
  • RequestPartsAlreadyExtracted
• <HeaderMap as FromRequest<_>>::Rejection has been changed to std::convert::Infallible.

breaking: axum::http::Extensions is no longer an extractor (ie it
doesn't implement FromRequest). The axum::extract::Extension extractor is
not impacted by this and works the same. This change makes it harder to
accidentally remove all extensions which would result in confusing errors
elsewhere (#699)
This includes these breaking changes:

• RequestParts::take_extensions has been removed.
• RequestParts::extensions returns &Extensions.
• RequestParts::extensions_mut returns &mut Extensions.
• RequestAlreadyExtracted has been removed.
• <Request as FromRequest>::Rejection is now BodyAlreadyExtracted.
• <http::request::Parts as FromRequest>::Rejection is now Infallible.
• ExtensionsAlreadyExtracted has been removed.

breaking: RequestParts::body_mut now returns &mut Option<B> so the
body can be swapped (#869)
