Struct WebSocketCapability 

#[non_exhaustive]
pub struct WebSocketCapability {
    pub url: String,
    pub supports_push: bool,
    pub extra: Map<String, Value>,
}

Capability object for "urn:ietf:params:jmap:websocket" (RFC 8887).

Advertised in Session.capabilities when the server supports JMAP over WebSocket. The url field is the wss:// endpoint to connect to.

extra equality is feature-flag-dependent (bd:JMAP-6r7c.43)

The derived PartialEq / Eq impl’s behaviour on the extra field depends on the global serde_json/preserve_order feature flag — see the crate-level note for the canonical statement.

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.

url: String

The WebSocket endpoint URL (wss://).

supports_push: bool

Whether the server supports push notifications over this WebSocket.

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).

Trait Implementations

impl Clone for WebSocketCapability

fn clone(&self) -> WebSocketCapability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WebSocketCapability

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WebSocketCapability

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for WebSocketCapability

impl PartialEq for WebSocketCapability

fn eq(&self, other: &WebSocketCapability) -> 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.
