    pub hook: Box<dyn ClientHook>,
}

An untyped client.

Fields

Implementations

impl Client

pub fn new(hook: Box<dyn ClientHook>) -> Self

pub fn new_call<Params, Results>( &self, interface_id: u64, method_id: u16, size_hint: Option<MessageSize> ) -> Request<Params, Results>

pub fn when_resolved(&self) -> Promise<(), Error>

If the capability is actually only a promise, the returned promise resolves once the capability itself has resolved to its final destination (or propagates the exception if the capability promise is rejected). This is mainly useful for error-checking in the case where no calls are being made. There is no reason to wait for this before making calls; if the capability does not resolve, the call results will propagate the error.
