Version

v0.8.1

Platform

UNIX

Crates

axum
axum-extra

Description

Now that the Host extractor was moved to the axum-extra crate and with the new changes to how Option extractors work, it's not possible to do something like this anymore:

use axum_extra::extract::Host;

async fn handler(host: Option<Host>){}

as the compiler complains with this error:

the trait bound `axum_extra::extract::Host: OptionalFromRequestParts<Arc<AppState>>` is not satisfied
you can use `cargo tree` to explore your dependency tree
required for `std::option::Option<axum_extra::extract::Host>` to implement `FromRequestParts<Arc<AppState>>`
