Struct ExtGift 

pub struct ExtGift<M: 'static>(/* private fields */);

A handle to a value registered via ExtContext::register, in a wire position that grants the peer a reference to it.

Uses a distinct Marker type parameter rather than the concrete stored type so the handle a caller holds does not need to name (or even know) the private type actually retained behind it — the same design dolang_rpc::session::Gift uses for its own object table.

Opaque by design: the direct/remote split is an implementation detail, not something extension authors match on.

Implementations

impl<M> ExtGift<M>

pub fn cite(&self) -> ExtCite<M>

Names this resource back to the endpoint that owns it, for a wire position that must not transfer a reference.

Panics

In remote mode, if this endpoint is itself the owner — see dolang_rpc::session::Gift::cite. Direct mode has no wire and no owner, so it cannot fail this way; extensions should still route through here so that the two modes agree.

Trait Implementations

impl<M> Clone for ExtGift<M>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'de, M: 'static> Deserialize<'de> for ExtGift<M>

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl<M: 'static> Serialize for ExtGift<M>

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
