Function dispatch_with 

pub fn dispatch_with<Detail>(
    event: &str,
    to: Option<&str>,
    detail: &Detail,
) -> Result<(), Error>
where
    Detail: Serialize + ?Sized,

Like dispatch, but attaches a serializable detail payload.

detail is serialized with serde_json and becomes event.detail on the CustomEvent seen by listeners.

Errors

Returns Error::Serialize if detail cannot be JSON-encoded. Also returns the same browser-bridge errors as dispatch.

Examples

Ad-hoc JSON:

use wasm_liveview as lv;

lv::dispatch_with(
    "wasm:score",
    Some("#score"),
    &serde_json::json!({ "delta": 5 }),
)?;

Typed payload via derive(Serialize):

use wasm_liveview as lv;

#[derive(serde::Serialize)]
struct ScoreDelta { delta: i32 }

lv::dispatch_with("wasm:score", Some("#score"), &ScoreDelta { delta: 5 })?;
