Function jsonrpsee_core::to_json_raw_value

pub fn to_json_raw_value<T>(value: &T) -> Result<Box<RawValue, Global>, Error>where
    T: Serialize + ?Sized,

Convert a T into a boxed RawValue.

Example

// Upstream crate
pub struct Thing {
    foo: String,
    bar: Option<String>,
    extra_data: Box<RawValue>,
}

// Local crate
use serde::Serialize;
use serde_json::value::{to_raw_value, RawValue};

#[derive(Serialize)]
struct MyExtraData {
    a: u32,
    b: u32,
}

let my_thing = Thing {
    foo: "FooVal".into(),
    bar: None,
    extra_data: to_raw_value(&MyExtraData { a: 1, b: 2 }).unwrap(),
};

Errors

This conversion can fail if T’s implementation of Serialize decides to fail, or if T contains a map with non-string keys.

use std::collections::BTreeMap;

// The keys in this map are vectors, not strings.
let mut map = BTreeMap::new();
map.insert(vec![32, 64], "x86");

println!("{}", serde_json::value::to_raw_value(&map).unwrap_err());
