Struct DeferredDispatcher 

pub struct DeferredDispatcher<D> { /* private fields */ }

A ConnectRPC dispatcher that can be initialized exactly once.

Tauri requires plugins that register URI schemes to be attached to the builder, but application services may depend on state created later in the app setup hook. Clone this dispatcher into the plugin’s service, then set the real dispatcher during setup.

Calls made before initialization are reported as unimplemented.

use connectrpc::{ConnectRpcService, Router};
use connectrpc_tauri::{DeferredDispatcher, serve};

let deferred = DeferredDispatcher::new();
fn plugin<R: tauri::Runtime>(
    deferred: DeferredDispatcher<Router>,
) -> tauri::plugin::TauriPlugin<R> {
    serve(ConnectRpcService::new(deferred))
}
let _service = ConnectRpcService::new(deferred.clone());
assert!(deferred.set(Router::new()).is_ok());

Implementations

impl<D> DeferredDispatcher<D>

pub fn new() -> Self

Creates an uninitialized dispatcher.

pub fn set(&self, dispatcher: D) -> Result<(), D>

Sets the dispatcher used for all subsequent calls.

Errors

Returns dispatcher unchanged if this instance was already initialized.

pub fn same_dispatcher(&self, other: &Self) -> bool

Returns true when both handles refer to the same deferred dispatcher.
