+# 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.
+
