Enum Arg 

pub enum Arg {
    Value(Value),
    Callback(Arc<dyn Fn(Vec<Value>) + Send + Sync + 'static>),
}

Argument type for RPC method calls.

Arguments can be either JSON values or callbacks. Callbacks are automatically encoded with the __callback__ prefix.

Example

use kkrpc::Arg;
use serde_json::json;
use std::sync::Arc;

// Value argument
let value_arg = Arg::Value(json!(42));

// Callback argument
let callback_arg = Arg::Callback(Arc::new(|args| {
    println!("Callback invoked with: {:?}", args);
}));

Variants

A JSON value argument

Callback(Arc<dyn Fn(Vec<Value>) + Send + Sync + 'static>)
