Struct Caller 

pub struct Caller { /* private fields */ }

Concrete caller type wrapping a DriverCaller with optional middleware.

This is the primary type for making outbound RPC calls. Generated *Client types store a Caller as a public field. Use with_middleware() to add client middleware to the call chain.

Implementations

impl Caller

pub fn new(driver: DriverCaller) -> Self

Create a new Caller wrapping a DriverCaller.

pub fn with_middleware( self, service: &'static ServiceDescriptor, middleware: impl ClientMiddleware, ) -> Self

Append a client middleware to this caller’s chain.

pub async fn call(&self, call: RequestCall<'_>) -> CallResult

Start one outgoing request attempt and wait for its response, running any registered middleware around the call.

pub async fn closed(&self)

Resolve when the underlying connection closes.

pub fn is_connected(&self) -> bool

Return whether the underlying connection is still considered connected.

pub fn channel_binder(&self) -> Option<&dyn ChannelBinder>

Return a channel binder for binding Tx/Rx handles in args before sending.
