Struct capnp_rpc::CapabilityServerSet
source · pub struct CapabilityServerSet<S, C>where
C: FromServer<S>,{ /* private fields */ }Expand description
Allows a server to recognize its own capabilities when passed back to it, and obtain the
underlying Server objects associated with them. Holds only weak references to Server objects
allowing Server objects to be dropped when dropped by the remote client. Call the gc method
to reclaim memory used for Server objects that have been dropped.

pub fn new() -> Self
sourcepub fn new_client(&mut self, s: S) -> C
pub fn new_client(&mut self, s: S) -> C
Adds a new capability to the set and returns a client backed by it.
sourcepub async fn get_local_server(
&self,
client: &C
) -> Option<Rc<RefCell<C::Dispatch>>>where
C: FromClientHook,
pub async fn get_local_server(
&self,
client: &C
) -> Option<Rc<RefCell<C::Dispatch>>>where
C: FromClientHook,
Looks up a capability and returns its underlying server object, if found. Fully resolves the capability before looking it up.

&self,

pub fn get_local_server_of_resolved(
&self,
client: &C
) -> Option<Rc<RefCell<C::Dispatch>>>where
C: FromClientHook,
Looks up a capability and returns its underlying server object, if found.
Does not attempt to resolve the capability first, so you will usually want
to call get_resolved_cap() before calling this. The advantage of this method
over get_local_server() is that this one is synchronous and borrows self
over a shorter span (which can be very important if self is inside a RefCell).
