Struct EncryptedBeacon 

pub struct EncryptedBeacon {
    pub node_id: NodeId,
    pub capabilities: u16,
    pub hierarchy_level: u8,
    pub battery_percent: u8,
}

Encrypted beacon for privacy-preserving advertisements

Contains node identification and status that can only be read by mesh members with the beacon key.

Fields

node_id: NodeId

Node identifier (encrypted in wire format)

capabilities: u16

Node capabilities bitmap (public)

hierarchy_level: u8

Hierarchy level (public, for parent selection)

battery_percent: u8

Battery percentage 0-100 (public)

Implementations

impl EncryptedBeacon

pub fn new( node_id: NodeId, capabilities: u16, hierarchy_level: u8, battery_percent: u8, ) -> Self

Create a new beacon with the given parameters

pub fn encrypt(&self, key: &BeaconKey, mesh_id_bytes: &[u8; 4]) -> Vec<u8>

Encrypt the beacon for transmission

Arguments

• key - Beacon encryption key from mesh genesis
• mesh_id_bytes - First 4 bytes of mesh_id hash (for identification)

Returns

21-byte encrypted beacon ready for BLE service data

pub fn decrypt(data: &[u8], key: &BeaconKey) -> Option<(Self, [u8; 4])>

Attempt to decrypt a beacon

Arguments

• data - Raw encrypted beacon bytes (21 bytes)
• key - Beacon encryption key to try

Returns

• Some((beacon, mesh_id_bytes)) if decryption succeeds and MAC is valid
• None if data is invalid or MAC doesn’t match (wrong mesh)

pub fn is_encrypted_beacon(data: &[u8]) -> bool

Check if data looks like an encrypted beacon (quick check)

Trait Implementations

impl Clone for EncryptedBeacon

fn clone(&self) -> EncryptedBeacon

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EncryptedBeacon

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for EncryptedBeacon

fn eq(&self, other: &EncryptedBeacon) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
