# Fix for Rust Edition 2024 Docker Build Error

## Problem

The error occurs because:
1. Your Dockerfile uses `FROM rust:latest` which pulled `rust:1.83-alpine`
2. Several dependencies require Rust 1.85+ for Edition 2024 support:
   - `time-core 0.1.8` requires Rust 1.88.0
   - `getrandom 0.4.1` requires Rust 1.85.0
   - `uuid 1.21.0` requires Rust 1.85.0
   - `deranged 0.5.6` requires Rust 1.85.0
   - `wasip2/wasip3` require Rust 1.87.0

## Root Cause

Rust Edition 2024 became stable in Rust 1.85.0 (released February 20, 2025).
Some of your transitive dependencies have updated to use Edition 2024,
which requires a newer Rust version than 1.83.

## Solutions

### ✅ RECOMMENDED: Update Rust Base Image

Change `FROM rust:latest` to `FROM rust:1.93` or newer.

**Pros:**
- Future-proof solution
- Gets latest Rust improvements and security fixes
- No dependency management overhead
- Standard practice (update base images regularly)

**Cons:**
- None (this is the correct approach)

### Alternative: Pin Dependency Versions (NOT RECOMMENDED)

Pin problematic dependencies to older versions that don't require Edition 2024.
This creates technical debt and should only be used if you have a specific
constraint preventing Rust version updates.
