Enum ErrorWrite 

pub enum ErrorWrite {
    NewRun,
    Refresh,
}

Whether a producer’s write is a fresh run or a live refresh.

EP.2/EP.3 (2026-08-10): the two are indistinguishable by looking at the entries — a language-server republish and a re-run compile can carry byte-identical lists — so the producer declares which it is and the host picks ErrorList::set or ErrorList::refresh.

Getting this wrong is user-visible: a refresh that resets snaps someone walking the list back to entry 1 on every keystroke.

Variants

NewRun

A fresh run — the user asked for new results and expects to start at the top. Compilation always sends this.

Refresh

A live update of an existing feed — keep the user where they were. The language server always sends this, including its first push (an empty list has nothing to anchor to, so it degrades to index 0 anyway).
