Struct ListPatch 

pub struct ListPatch<S> { /* private fields */ }

Item changes to list signals of S, sent without the rest of each list.

Build one with Sig::patch_append, Sig::patch_prepend, Sig::patch_upsert, or Sig::patch_remove, and combine with ListPatch::and. The browser applies the changes in order to the list it holds, so a list the server sends one message of at a time grows in the browser without the server keeping a copy of it.

use serde::{Deserialize, Serialize};

#[derive(Signals, Serialize, Deserialize)]
struct Message {
    body: String,
}

#[derive(Signals, Serialize, Deserialize)]
struct Room {
    messages: Vec<Message>,
}

let hello = Message { body: "hello".into() };
let patches: Patches<Room> = Room::messages().patch_append(&[hello]).into();
assert_eq!(
    patches.to_event_stream(),
    "event: hs-list\ndata: [\"append\",\"messages\",[\"lit\",[{\"body\":\"hello\"}]]]\n\n",
);
