Enum SseEvent 

#[non_exhaustive]
pub enum SseEvent {
    StateChange(StateChange),
    Unknown {
        event_type: String,
        data: String,
    },
}

A parsed SSE event from a JMAP event source (RFC 8620 §7.3).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

StateChange(StateChange)

A “state” event: maps accountId → (typeName → newState).

Triggers a /changes call for each type listed. Wire format: {"@type":"StateChange","changed":{"<accountId>":{"<TypeName>":"<state>"}}}

Unknown

Unrecognized event type, keepalive, or parse failure.

event_type carries the value of the SSE event: field for diagnostics — e.g. "ping" for a keepalive, "state" when the state payload failed to parse. An empty string means the frame had no event: field (a keepalive comment or bare data).

Callers should silently ignore this variant; log event_type when debugging unexpected parse failures.

Fields

event_type: String

Value of the SSE event: field. Empty string when the frame had no event: line (e.g. a keepalive comment or bare data block).

data: String

Raw concatenated value of the SSE data: field(s), with the leading space stripped per RFC 8895 §9.1.

Trait Implementations

impl Clone for SseEvent

fn clone(&self) -> SseEvent

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SseEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for SseEvent

impl PartialEq for SseEvent

fn eq(&self, other: &SseEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
