Struct ClosureHandler 

pub struct ClosureHandler<B: Send + Sync + 'static> {
    pub backend: Arc<B>,
    pub call_fn: Box<BackendCallFn<B>>,
}

A JmapHandler that wraps an async closure over a shared backend.

CallerCtx limitation

The closure receives (args: Value, ctx: C) where C is the caller context (e.g. auth identity). However, the closures registered via [register_mail_handlers] / [register_chat_handlers] capture the backend via Arc and ignore ctx entirely — they do not forward the auth context to the handler.

If per-request auth context is needed, register handlers individually via Dispatcher::register with a closure that explicitly uses ctx. Adding CallerCtx forwarding to ClosureHandler itself would be a breaking API change, deferred to a future version.

Fields

backend: Arc<B>

call_fn: Box<BackendCallFn<B>>

Trait Implementations

impl<B: Send + Sync + 'static, C: Clone + Send + 'static> JmapHandler<C> for ClosureHandler<B>

fn call( &self, _method: String, call_id: String, args: Value, _caller: C, ) -> HandlerFuture

method is the registered method name for this call. A single handler instance may be registered under multiple names (e.g. both "Foo/get" and "Bar/get"); this parameter lets the handler distinguish between them.
