Extension trait for ZoneState with CRDT operations

Uses multiple CRDT types for distributed consistency:

Commander: LWW-Register (Last-Write-Wins)
Cells: OR-Set (Observed-Remove Set)
Capabilities: G-Set (Grow-only Set)

§Example

use peat_protocol::models::zone::{ZoneConfig, ZoneConfigExt, ZoneState, ZoneStateExt};

let config = ZoneConfig::new("zone_1".to_string(), 10);
let mut zone = ZoneState::new(config);

// Add cells to zone
zone.add_cell("cell_alpha".to_string());
zone.add_cell("cell_beta".to_string());

assert_eq!(zone.cell_count(), 2);
assert!(zone.is_valid()); // Meets minimum cells

Required Methods§

Source

fn new(config: ZoneConfig) -> Self

Create a new zone state from configuration

§Example

use peat_protocol::models::zone::{ZoneConfig, ZoneConfigExt, ZoneState, ZoneStateExt};

let config = ZoneConfig::new("zone_north".to_string(), 5);
let zone = ZoneState::new(config);

Source

fn add_cell(&mut self, cell_id: String) -> bool

Add a cell to the zone (OR-Set add operation)

Returns true if cell was added, false if already present or zone is full.

§Example

use peat_protocol::models::zone::{ZoneConfig, ZoneConfigExt, ZoneState, ZoneStateExt};

let config = ZoneConfig::new("zone_1".to_string(), 3);
let mut zone = ZoneState::new(config);

assert!(zone.add_cell("cell_1".to_string()));
assert!(!zone.add_cell("cell_1".to_string())); // Already present
