Struct matrix_sdk::event_handler::RawEvent

pub struct RawEvent(pub Box<RawJsonValue>);

The raw JSON form of an event.

Used as a context argument for event handlers (see Client::register_event_handler).

Tuple Fields

0: Box<RawJsonValue>

Methods from Deref<Target = RawJsonValue>

pub fn get(&self) -> &str

Access the JSON text underlying a raw value.

Example

use serde::Deserialize;
use serde_json::{Result, value::RawValue};

#[derive(Deserialize)]
struct Response<'a> {
    code: u32,
    #[serde(borrow)]
    payload: &'a RawValue,
}

fn process(input: &str) -> Result<()> {
    let response: Response = serde_json::from_str(input)?;

    let payload = response.payload.get();
    if payload.starts_with('{') {
        // handle a payload which is a JSON map
    } else {
        // handle any other type
    }

    Ok(())
}

fn main() -> Result<()> {
    process(r#" {"code": 200, "payload": {}} "#)?;
    Ok(())
}
