Struct capnp_rpc::CapabilityServerSet

pub struct CapabilityServerSet<S, C>where
    C: FromServer<S>,{ /* private fields */ }

Allows a server to recognize its own capabilities when passed back to it, and obtain the underlying Server objects associated with them.

Implementations

impl<S, C> CapabilityServerSet<S, C>where
    C: FromServer<S>,

pub fn new() -> Self

pub fn new_client(&mut self, s: S) -> C

Adds a new capability to the set and returns a client backed by it.

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.

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).

fn default() -> Self

Returns the “default value” for a type.
