Enum WatchEvent 

pub enum WatchEvent {
    EnvelopeAdded {
        mailbox: String,
        envelope: Envelope,
    },
    EnvelopeRemoved {
        mailbox: String,
        id: String,
    },
    FlagsAdded {
        mailbox: String,
        id: String,
        flags: BTreeSet<Flag>,
    },
    FlagsRemoved {
        mailbox: String,
        id: String,
        flags: BTreeSet<Flag>,
    },
    KeepAlive,
}

Delta produced by a watch-mailbox stream.

mailbox is the watched mailbox name (always the same value for the lifetime of a single stream). Flag deltas are split into FlagsAdded and FlagsRemoved so hook configs can target one side of a toggle (e.g. “fire when \Seen is added”).

Variants

EnvelopeAdded

A new message landed in the watched mailbox.

Fields

mailbox: String

envelope: Envelope

EnvelopeRemoved

An existing message was expunged from the watched mailbox.

Fields

mailbox: String

id: String

FlagsAdded

One or more flags were set on an existing message.

Fields

mailbox: String

id: String

flags: BTreeSet<Flag>

FlagsRemoved

One or more flags were unset on an existing message.

Fields

mailbox: String

id: String

flags: BTreeSet<Flag>

KeepAlive

The transport is still alive but had no changes to report. Useful for callers that want to distinguish “stream healthy” from “stream stalled” without arming their own timer.
