Struct QuotaExceededError 

pub struct QuotaExceededError(pub String);

Marker for a host failure that should surface to the guest as the built-in QuotaExceededError subclass rather than a base Error. Return Err(quota_exceeded_error(...)) from a host-fn body; the register_host_fn wrapper downcasts for it when converting the Err into a guest throw. The message is the guest-visible e.message.
