Trait DocumentStore 

pub trait DocumentStore: Send + Sync {
    // Required methods
    fn save(&mut self, doc: &HiveDocument) -> Result<()>;
    fn load(&self) -> Result<Option<HiveDocument>>;
    fn clear(&mut self) -> Result<()>;

    // Provided method
    fn has_document(&self) -> bool { ... }
}

Trait for persisting HIVE documents

Implementations of this trait provide durable storage for mesh state, allowing nodes to recover their document after restarts.

Implementation Notes

• save() should be called after significant state changes (new peers, emergencies)
• load() should be called during mesh initialization
• Implementations should handle concurrent access safely
• Consider encryption for sensitive deployment scenarios

Required Methods

fn save(&mut self, doc: &HiveDocument) -> Result<()>

Save the current document to persistent storage

This should serialize the document and write it to durable storage. Implementations should handle errors gracefully and return appropriate error types.

fn load(&self) -> Result<Option<HiveDocument>>

Load a previously saved document

Returns Ok(Some(doc)) if a document was found, Ok(None) if no document exists (first run), or Err if loading failed.

fn clear(&mut self) -> Result<()>

Clear any stored document

Use this for factory reset or when leaving a mesh.

Provided Methods

fn has_document(&self) -> bool

Check if a document is stored
