Derive Macro display_json::DebugAsJson

#[derive(DebugAsJson)]

Implements Debug as a wrapper around serde_json::to_string.

See this crate’s documentation for more examples on how you can use this custom derive procedural macro.

Example:

use serde::Serialize;
use display_json::DebugAsJson;

#[derive(Serialize, DebugAsJson)]
#[serde(tag = "type")]
#[serde(content = "val")]
#[serde(rename_all = "lowercase")]
enum EitherStringOrNum {
  String(String),
  Num(f64),
}

let num = EitherStringOrNum::Num(12.);
assert_eq!(format!("{:?}", num), r#"{"type":"num","val":12.0}"#);

let string = EitherStringOrNum::String("hello".to_owned());
assert_eq!(
  format!("{:?}", string),
  r#"{"type":"string","val":"hello"}"#,
);
