How to use: JSON to Rust Struct

Description

Generate a serde-derived Rust struct with rename attributes from a JSON sample.

• Data Conversion Tools
• Because everything is computed client-side, JSON to Rust Struct is safe to use with sensitive data such as API keys, tokens or private logs.

How to use

Using JSON to Rust Struct takes three steps:

1. Paste your data into the input box (or load the example).
2. Configure the options to match your target format or scenario.
3. Copy, download or inspect the output — it updates live as you type.

Run

Examples

Emits serde rename attributes so the Rust field names can stay idiomatic.

Input

{"id":42,"title":"Hello","tags":["a","b"],"active":true}

Output

use serde::{Deserialize, Serialize};

#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct Root {
    #[serde(rename = "id")]
    pub id: i64,
    #[serde(rename = "title")]
    pub title: String,
    #[serde(rename = "tags")]
    pub tags: Vec<String>,
    #[serde(rename = "active")]
    pub active: bool,
}

Use cases

Common situations where JSON to Rust Struct helps:

• Generate a serde-derived Rust struct with rename attributes from a JSON sample.

Parameters

This tool has no options — it works on the input alone.

FAQ

Good to know

• Everything runs client-side, so extremely large inputs are limited by your browser tab’s memory rather than by a server upload limit.
