Crate alpe_core 

alpe-core

Core domain types, error hierarchy, and pure business logic for the Alpe platform.

This crate is the foundation of the Alpe architecture. It contains zero IO — all types and functions are pure, deterministic, and 100% unit-testable. Every other crate in the workspace depends on alpe-core.

Modules

• error — Unified error hierarchy (error::CoreError, error::ValidationError, error::TransitionError)
• jurisdiction — EU member state types and sovereignty replication rules
• resource — Resource state machine and metadata
• validation — Input validation (DNS label constraints for names)
• plan — Compute and database service plans with resource limits
• project — Project specification and validation

Design Principles

• Pure logic: No IO, no async, no side effects — every function is deterministic
• Type safety: Invalid states are unrepresentable where possible
• Test-first: All modules are developed with strict TDD (RED → GREEN → Refactor)
• Documentation as code: #![deny(missing_docs)] enforces documentation on every public item
