pub struct Any;
Expand description
A passthrough marker message type.
This is a special message type which will enable your worker to accept any typed message, by ignoring the type information in the payload.
This is especially useful for implementing middleware workers which need access to the route information of a message, without understanding its payload.
§Examples
ⓘ
use ockam::{hex, Any, Context, Result, Routed, Worker};
pub struct Logger;
#[ockam::worker]
impl Worker for Logger {
type Context = Context;
type Message = Any;
/// This Worker will take any incoming message, print out the payload
/// and then forward it to the next hop in its onward route.
async fn handle_message(&mut self, ctx: &mut Context, msg: Routed<Any>) -> Result<()> {
let mut local_msg = msg.into_local_message();///
let payload = local_msg.payload_ref();
if let Ok(str) = String::from_utf8(payload.to_vec()) {
println!("Address: {}, Received string: {}", ctx.address(), str);
} else {
println!("Address: {}, Received binary: {}", ctx.address(), hex::encode(&payload));
}
ctx.forward(local_msg).await
}
}
