This seems to be fine for me, does the compilation error happen on nightly? If not, which compiler version and environment are we talking about?

[subhojit777]

rustc 1.30.1 (1433507eb 2018-11-07)

I am working on the dev-v0.4.0 branch.

Weird, I can't replicate it with exactly the same compiler version.

Maybe your work is based on some intermediate commit in a longer commit series. Can you try to base your work on the tag v0.4.0-preview.0? Note that the development branch is expected to change a lot, including breaking changes and non-compiling versions but only all tagged versions (aka. those published to <crates.io>) should work correctly. Still, your patch seems to be based on commit e6211cb which I can compile fine.

I'm a bit puzzled to be honest.

Edit: it could still be useful to apply these patches but the scope-list may as well be included in the state of the actix app then. Or maybe even create a simple wrapper struct, whichever is clearer. The current version was more a proof of concept, it needs to be improved at some point.

I was not able to compile with the 0.4.0-preview.0 version. There is a conflict with ring crate - #15 (comment)

Sorry that I never got around to this as it was a preview version and I could reproduce it. This should not happen in v0.4 release.
