implementing `serde_json` serialization of enum variants in Rust with custom attributes
This might be a silly question, but This might be a silly question, but After trying multiple solutions online, I still can't figure this out. I'm having trouble serializing an enum with custom attributes using `serde_json`. I defined an enum with different variants that have associated data, and I want to serialize it to JSON, but I'm working with unexpected behavior. My enum looks like this: ```rust use serde::{Serialize, Deserialize}; #[derive(Serialize, Deserialize, Debug)] enum MyEnum { VariantA { value: i32 }, VariantB { value: String }, } ``` When I try to serialize an instance of `MyEnum`, like so: ```rust fn main() { let instance = MyEnum::VariantA { value: 42 }; let json = serde_json::to_string(&instance); match json { Ok(json_str) => println!("Serialized: {}", json_str), Err(e) => eprintln!("Serialization behavior: {}", e), } } ``` I get the following behavior message: ``` behavior: expected an identifier, found `{` ``` I thought I had everything set up correctly, and I've made sure to include `serde` and `serde_json` in my `Cargo.toml` like this: ```toml [dependencies] serde = { version = "1.0", features = ["derive"] } serde_json = "1.0" ``` I've tried various combinations of the attributes on the enum, including adding `#[serde(tag = "type")]`, but nothing seems to resolve this. Could anyone guide to understand why I'm working with this behavior and how to serialize my enum properly? Any guidance on best practices would also be appreciated. This is part of a larger CLI tool I'm building. Am I missing something obvious? This is part of a larger CLI tool I'm building. Thanks for your help in advance! Has anyone else encountered this?
