`cargo install https` warning

[rickhg12hs]

Near the end of cargo install https, the following warning is shown:

warning: the following packages contain code that will be rejected by a future version of Rust: traitobject v0.1.0
note: to see what the problems were, use the option `--future-incompat-report`, or run `cargo report future-incompatibilities --id 1`

Version info:

$ cargo --version
cargo 1.72.0 (103a7ff2e 2023-08-15)
$ rustc --version
rustc 1.72.0 (5680fa18f 2023-08-23)

Yeah I've been seeing this in the builds since at least https://debian.nabijaczleweli.xyz/builds/http_1.13.0-1_amd64.build (2023-07-15 19:27:52). Apparently it's rust-lang/rust#56484 (comment). Very cool and normal to break existing code for no reason. Will burn that bridge when it comes to it.

@nabijaczleweli Has that bridge arrived?

error: failed to compile `https v2.2.0 (https://github.com/thecoshman/http.git#dff87d17)`, intermediate artifacts can be found at `/tmp/cargo-installzwgIUe`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

Certainly looks like it! Thanks for the fix in #171, this will be released in 2.2.1.
