Struct Replaced 

pub struct Replaced {
    pub dropped: Vec<String>,
    pub kept: Vec<String>,
    pub added: Vec<String>,
}

What Htl::replace_bundle did, so a host can say it rather than guess.

Three lists because three things happen to a name, and a host that logs “reloaded” for all of them is hiding the two that matter: a module that went away for good, and one whose live value was deliberately spared.

A module both bundles carry appears in dropped and in added — which is what happened to it: the old one was taken out of package.loaded, and the new one is what the next require will evaluate. Nothing is in both dropped and kept.

Fields

dropped: Vec<String>

Names the old bundle had installed that are now out of package.preload and package.loaded: the next require of one evaluates whatever answers it now, and for a name the new bundle does not carry there may be nothing left to answer.

kept: Vec<String>

Names from keep that the old bundle had actually installed, and whose evaluated value is still in package.loaded. Shorter than the keep that was asked for when a name in it was never this bundle’s — the host’s own module, or a typo — which is the only report of that.

added: Vec<String>

Names the new bundle wrote into package.preload. Not what it carries: a name the host had registered first is still the host’s and is not here.
