Which crate dependencies are required for this generated code?

The generated code requires the standard serde crate with the derive feature enabled. Add this to your Cargo.toml: serde = { version = '1.0', features = ['derive'] } and serde_json = '1.0'.

What is the JSON to Rust Struct Converter?

The PriyGop JSON to Rust Struct Converter transforms JSON documents into rigorously typed, memory-safe Rust structs. It generates standard serde derives, applies #[serde(rename = "...")] attributes when JSON keys differ from Rust's idiomatic snake_case, and utilizes Option<T> for nullable and optional fields.

Rust Generation Standards

Serde Derives: Automatically adds #[derive(Debug, Clone, Serialize, Deserialize)].
Field Renaming: Applies #[serde(rename = "...")] whenever keys use camelCase, hyphens, or reserved keywords.
Skip None on Serialize: Optionally adds #[serde(skip_serializing_if = "Option::is_none")].
Raw Identifiers: Uses r#type syntax to safely escape Rust reserved keywords without breaking serialization.

Supported Formats & Syntax Examples

Common input data types and real-world representations supported by this tool.

Serde Struct with Renaming

Rust

Derives with attribute renaming and Option handling.

Example Syntax

use serde::{Deserialize, Serialize};

#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct User {
    #[serde(rename = "user_id")]
    pub user_id: i64,

    #[serde(rename = "email_address")]
    pub email_address: String,

    #[serde(skip_serializing_if = "Option::is_none")]
    pub nickname: Option<String>,
}

Compiles cleanly with cargo check and standard serde 1.0 dependencies.
