Enum EnvelopeDiff 

pub enum EnvelopeDiff {
    FullListRequired {
        new_state: Option<Vec<u8>>,
    },
    Incremental {
        new_state: Vec<u8>,
        flag_updates: Vec<FlagUpdate>,
        new_envelopes: Vec<Envelope>,
        vanished_ids: Vec<String>,
    },
}

Outcome of an incremental envelope-diff call.

new_state is the opaque per-backend checkpoint to persist for the next call; format is private to the backend impl (IMAP packs (uid_validity, highest_mod_seq, highest_uid); JMAP stores the raw Email/state bytes). Callers treat it as a Vec<u8> blob.

Variants

FullListRequired

First sync, server-side state invalidated, or capability missing. The caller must fall back to a regular list_envelopes round-trip and treat the result as the new baseline. new_state may be None when the backend could not cheaply capture a baseline without listing.

Fields

new_state: Option<Vec<u8>>

Incremental

The backend returned a pre-diffed delta. The three buckets are disjoint; the caller applies them against the stored ancestor.

Fields

new_state: Vec<u8>

flag_updates: Vec<FlagUpdate>

new_envelopes: Vec<Envelope>

vanished_ids: Vec<String>
