Implementations

impl ClientDatabase

pub fn load(file_path: &Path, network_config: VpnNetworkConfig) -> Result<Self>

Load or create client database from file

pub fn save(&self) -> Result<()>

Save database to file

pub fn add_client(&self, name: &str) -> Result<ClientConfig>

Add a new client, returns the generated config

pub fn network_config(&self) -> VpnNetworkConfig

pub fn remove_client(&self, client_id: &str) -> Result<()>

Remove a client by ID

pub fn list_clients(&self) -> Vec<ClientConfig>

Get all clients

pub fn find_by_psk(&self, psk: &[u8; 32]) -> Option<ClientConfig>

Find client by PSK (used during handshake to identify the connecting client)

pub fn find_by_vpn_ip(&self, ip: &Ipv4Addr) -> Option<ClientConfig>

Find client by VPN IP

pub fn find_by_id(&self, id: &str) -> Option<ClientConfig>

Find client by ID

pub fn record_handshake(&self, client_id: &str)

Update client stats (called from gateway on traffic)

pub fn record_traffic(&self, client_id: &str, bytes_in: u64, bytes_out: u64)

Update traffic counters

pub fn flush_stats(&self)

Persist stats periodically (called from a background task)

pub fn reload_if_changed(&self) -> bool

Reload client database from disk if the file has changed. Preserves in-memory traffic stats for existing clients. Returns true if the client configuration changed.
