Struct ChatPushCapability 

#[non_exhaustive]
pub struct ChatPushCapability {
    pub max_snippet_bytes: u64,

Account-level capability object for "urn:ietf:params:jmap:chat:push".

Found at accounts[id].accountCapabilities["urn:ietf:params:jmap:chat:push"].

Spec: draft-atwood-jmap-chat-push-00

Strictness

The struct-level #[serde(default)] is deliberately NOT present: max_snippet_bytes and supported_urgency_values are spec-required (draft-atwood-jmap-chat-push-00 lines 90-94). max_messages_per_push is the only optional field (line 96) and is already Option<u64>. A server returning {} for this capability is non-compliant; consumers surface that via a deserialize error rather than silently defaulting max_snippet_bytes to 0 (which would force every bodySnippet to be truncated to nothing).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_snippet_bytes: u64

Maximum byte length of a bodySnippet in ChatMessagePush. Truncation occurs on a UTF-8 boundary.

supported_urgency_values: Vec<UrgencyLevel>

Supported Web Push urgency values. MUST include at least UrgencyLevel::Normal and UrgencyLevel::High.

Element type is UrgencyLevel rather than String so callers can match on the typed variants directly. Canonical wire strings ("very-low", "low", "normal", "high") deserialize to typed variants; unknown wire strings land in UrgencyLevel::Other per the impl_string_enum! round-trip contract.

max_messages_per_push: Option<u64>

Maximum number of ChatMessageEntry objects per push payload. None means the server does not impose a bound.

extra: Map<String, Value>

Catch-all for vendor / site / private extension fields not covered by the typed fields above. Preserves unknown fields across deserialize/serialize round-trip per workspace extras-preservation policy (see workspace AGENTS.md).
