Hi 👋🏻 I'm trying write structured logs, but somehow the key/values seem to be ignored...

I have this in my Cargo.toml:

[dependencies]
env_logger = "0.10"
log = { version = "0.4.17", features = ["kv_unstable"] }

And this is main.rs:

use log::info;

fn main() {
    env_logger::builder()
        .filter_level(log::LevelFilter::Info)
        .init();
    info!(some = "thing"; "Hello, world!");
}

And when I run this I get this:

Any ideas? Am I missing anything or doing something wrong?

Thanks!
