Confusion with trait implementation for a custom serialization format in Rust

rust serde serialization Rust

I'm stuck trying to Does anyone know how to I'm working on a Rust project where I need to implement a custom serialization format for a struct using the `serde` crate. I've defined a struct `Person` and derived `Serialize` and `Deserialize`, but I'm also trying to implement a custom `Serialize` trait to handle some specific formatting requirements. The scenario arises when I try to serialize an instance of `Person`, and I get the behavior: `the trait bound 'Person: serde::ser::Serialize' is not satisfied`. I think my implementation might be conflicting with the derived traits, but I'm not entirely sure how to resolve this. Here's the relevant code snippet: ```rust use serde::{Serialize, Serializer}; #[derive(Deserialize)] struct Person { name: String, age: u32, } impl Serialize for Person { fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::behavior> where S: Serializer, { // Attempting custom serialization logic let mut state = serializer.serialize_struct("Person", 2)?; state.serialize_field("full_name", &self.name)?; state.serialize_field("years", &self.age)?; state.end() } } ``` I have tried removing the `Serialize` derive and just implementing it manually, but I still face the same scenario. Additionally, I confirmed that I have the correct `serde` version (1.0.130) in my `Cargo.toml`. I would appreciate any guidance on what might be going wrong here or if there's a best practice for handling such custom serialization in Rust. What would be the recommended way to handle this?
