actix example doesn't work (resolved)

[rj-xy]

Hi,

I'm trying to get the actix example working in it's own new project.

But I get the following error:

no method named as_ref found for type mime_guess::Mime in the current scope
src/main.rs:22:61

$ cargo build 
Compiling embed_actix v0.1.0 (/home/rj/src/embed_actix)
error[E0599]: no method named `as_ref` found for type `mime_guess::Mime` in the current scope
--> src/main.rs:22:61
   |
22 |       HttpResponse::Ok().content_type(guess_mime_type(path).as_ref()).body(body)`
   |                                                             ^^^^^

cargo.toml:

[package]
name = "embed_actix"
version = "0.1.0"
authors = ["me <me@test.com>"]
edition = "2018"

[dependencies]
actix-web = "0.7.19"
rust-embed = "4.4.0"
mime_guess = "1.8.7"

src/main.rs is copy of (with no changes):
examples/actix.rs

Mime is defined as

#[derive(Clone, Debug, Eq, Hash, Ord, PartialOrd)]
pub struct Mime<T: AsRef<[Param]> = Vec<Param>>(pub TopLevel, pub SubLevel, pub T);

so should have the as_ref trait?

Any help to get this working would be great - thanks!

Found the problem - I was using a stable version of mime_guess, when I should have been using the latest alpha version. So my cargo.toml file looks like this (main.rs (copy of examples/actix.rs) is untouched):

[package]
name = "embed_actix"
version = "1.0.0"
authors = ["me <me@test.com>"]
edition = "2018"

[dependencies]
actix-web = "0.7"
mime_guess = "2.0.0-alpha.6"
rust-embed = "4.4.0"
