tomevault-io Rust — SOLID and hexagonal
SOLID mapped to Rust
| Principle | In Rust |
|---|---|
| SRP | Focused crates/modules/impl; cohesive use-case types |
| OCP | New enum variants or new impl Trait for Struct |
| LSP | Trait impls honor docs; no surprising panics in “total” methods |
| ISP | Several small traits under ports/, not one huge persistence trait |
| DIP | Core defines traits; infrastructure implements them |
Layout in this kind of monorepo
- Domain / core: entities, rules, repository and transport traits.
- Adapters: sqlite, udp, … — only here do drivers and external schema strings appear.
- Runtime / binary: wires concrete implementations into the core.
Checklist when adding a capability
- Does core import any I/O crate? → hide it behind a trait.
- Does the trait force adapters to know too much internal detail? → split the trait (ISP).
- Does an adapter change break domain tests? → domain tests should use fakes or test doubles for traits, not real SQLite.
