ICE D:

error: internal compiler error: unexpected panic

this seems wierd, I can replicate myself, but can't replicate with another library/crate, trying to find the cause to file an issue (if applicable)

it's this https://github.com/GuillaumeGomez/rust/blob/a5213888e04b6bacda5198dc41026b604fe410ef/src/librustdoc/html/render/print_item.rs#L943

edit: probably some wierd state I have, going to try and find out where it is, features ftw :D
edit2: it's pubsub, now to pinpoint the cause
edit3: pubsub + unsupported
edit4: can't even replicate with pubsub in its own crate
edit5: managed to get it again, now to see what it is...

found it. rust-lang/rust#88600

tried to fix it with something like this

// Custom default trait because I don't want to make T a real Default.
trait CustomDefault {
    fn custom_default() -> Self;
}

impl CustomDefault for HypeTrainCooldownExpiration{
    fn custom_default() -> Self {
        HypeTrainCooldownExpiration { }
    }
}

#[derive(Debug, Clone, Serialize, Deserialize, PartialEq, Eq)]
#[cfg_attr(feature = "deny_unknown_fields", serde(deny_unknown_fields))]
#[non_exhaustive]
pub struct HypeTrainCooldownExpiration {}

#[derive(Deserialize)]
pub enum HypeTrainEventsV1Reply {
    #[serde(default = "CustomDefault::custom_default", "rename = "hype-train-cooldown-expiration")]
    HypeTrainCooldownExpiration(HypeTrainCooldownExpiration),
}

but that doesn't work. serde-rs/serde#2088

While waiting for a fix in rustdoc, I'll make the field not hidden and make it use a real struct for content and wrap it with an option, in case there ever will be content attached to the event.
