overhaul dioxus fullstack using a new implementation of server_fn This PR is a complete rewrite of dioxus fullstack designed to improve compatibility with axum and to fix a number of compilation errors based on feature flag unification plumbing through macros.

//! This example shows how you can extract a HeaderMap from requests to read custom headers.
|
|
//!
|
|
//! The extra arguments in the `#[get(...)]` macro are passed to the underlying axum handler,
|
|
//! and only visible on the server. This lets you run normal axum extractors like `HeaderMap`,
|
|
//! `TypedHeader`, `Query`, etc.
|
|
//!
|
|
//! Note that headers returned by the server are not always visible to the client due to CORS.
|
|
//! Headers like `Set-Cookie` are hidden by default, and need to be explicitly allowed
|
|
//! by the server using the `Access-Control-Expose-Headers` header (which dioxus-fullstack does not
|
|
//! currently expose directly).
