go2rs

What is go2rs?

• go2rs is a Rust struct generator from Go structs
• Automatically recognizes Go modules in the directory and generates equivalent Rust types
• Handles Go-to-Rust type conversions with appropriate derives and attributes

Installation

$ go get github.com/drewstone/go2rs

Usage

// ./example/main.go
package main

import (
    "time"
)

type Status string

const (
    StatusOK Status = "OK"
    StatusFailure Status = "Failure"
)

type Param struct {
    Status    Status
    Version   int
    Action    string
    CreatedAt time.Time
}

$ go2rs ./example

Generates:

use serde::{Deserialize, Serialize};
use chrono::{DateTime, Utc};

#[derive(Debug, Clone, Serialize, Deserialize)]
#[serde(rename_all = "PascalCase")]
pub enum Status {
    OK,
    Failure,
}

#[derive(Debug, Clone, Serialize, Deserialize)]
#[serde(rename_all = "PascalCase")]
pub struct Param {
    pub status: Status,
    pub version: i32,
    pub action: String,
    #[serde(with = "chrono::serde::ts_seconds")]
    pub created_at: DateTime<Utc>,
}

Features

• Converts Go types to idiomatic Rust types
• Handles common Go patterns like string enums
• Adds appropriate serde derives and attributes
• Supports time.Time conversion to chrono::DateTime
• Maintains field visibility and naming conventions
• Generates documentation from Go comments

TODO

• Handle custom MarshalJSON/UnmarshalJSON implementations
