Struct NodeId 

pub struct NodeId { /* private fields */ }

Node identifier

Represents a unique node in the HIVE mesh. For BLE, this is typically derived from the Bluetooth MAC address or a configured value.

Implementations

impl NodeId

pub fn new(id: u32) -> Self

Create a new node ID from a 32-bit value

pub fn as_u32(&self) -> u32

Get the raw 32-bit ID value

pub fn parse(s: &str) -> Option<Self>

Create from a string representation (hex format)

pub fn from_mac_address(mac: &[u8; 6]) -> Self

Derive a NodeId from a BLE MAC address.

Uses the last 4 bytes of the 6-byte MAC address as the 32-bit node ID. This provides a consistent node ID derived from the device’s Bluetooth hardware address.

Arguments

• mac - 6-byte MAC address array (e.g., [0xAA, 0xBB, 0xCC, 0xDD, 0xEE, 0xFF])

Example

use hive_btle::NodeId;

let mac = [0x00, 0x11, 0x22, 0x33, 0x44, 0x55];
let node_id = NodeId::from_mac_address(&mac);
assert_eq!(node_id.as_u32(), 0x22334455);

pub fn from_mac_string(mac_str: &str) -> Option<Self>

Derive a NodeId from a MAC address string.

Parses a MAC address in “AA:BB:CC:DD:EE:FF” format and derives the node ID from the last 4 bytes.

Arguments

• mac_str - MAC address string in colon-separated hex format

Returns

Some(NodeId) if parsing succeeds, None otherwise

Example

use hive_btle::NodeId;

let node_id = NodeId::from_mac_string("00:11:22:33:44:55").unwrap();
assert_eq!(node_id.as_u32(), 0x22334455);

Trait Implementations

impl Clone for NodeId

fn clone(&self) -> NodeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeId

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

Formats the value using the given formatter.

impl Default for NodeId

fn default() -> NodeId

Returns the “default value” for a type.

impl Display for NodeId

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

Formats the value using the given formatter.

impl From<NodeId> for u32

fn from(node_id: NodeId) -> Self

Converts to this type from the input type.

impl From<u32> for NodeId

fn from(id: u32) -> Self

Converts to this type from the input type.

impl Hash for NodeId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NodeId

fn cmp(&self, other: &NodeId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NodeId

fn eq(&self, other: &NodeId) -> 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.

impl PartialOrd for NodeId

fn partial_cmp(&self, other: &NodeId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
