Struct NodeIdentityProfile 

pub struct NodeIdentityProfile {
    pub public_key: PublicKey,
    pub role: NodeRole,
    pub capabilities: NodeCapabilities,
    pub name: Option<String>,
    pub location: Option<NodeLocation>,
    pub altitude_m: Option<i32>,
    pub supported_regions: Option<Vec<u8>>,
    pub clock: fn() -> Option<u32>,
}

This node’s own identity, used to answer Identity Requests.

Holds descriptive fields only — no signing key. Config-like fields (role, capabilities, name, supported_regions) are typically set once at bring-up; live fields (location, altitude_m) can be refreshed at any time via LocalNode::update_identity_profile, e.g. from a GPS task.

Fields

public_key: PublicKey

This node’s public key. Its hint is matched against a request’s FILTER_NODE_HINT; the key itself reaches the requester via the reply’s MAC source address, not the identity payload.

role: NodeRole

capabilities: NodeCapabilities

name: Option<String>

location: Option<NodeLocation>

altitude_m: Option<i32>

supported_regions: Option<Vec<u8>>

clock: fn() -> Option<u32>

Where identity option 3 comes from: the current Unix time, or None on a node that does not know what time it is.

A source rather than a value, because option 3 dates the payload and every payload is built fresh — a stored number would be the time some earlier payload was built. It lives here so that the one canonical builder stamps every framing identically; a node with no clock keeps the default and simply omits the option.

Implementations

impl NodeIdentityProfile

pub fn new( public_key: PublicKey, role: NodeRole, capabilities: NodeCapabilities, ) -> Self

Create a minimal profile (role + capabilities), no descriptive options.

pub fn with_name(self, name: impl Into<String>) -> Self

Set the display name (builder style).

pub fn with_location(self, location: NodeLocation) -> Self

Set the geographic location (builder style).

pub fn hint(&self) -> NodeHint

This node’s hint, derived from its public key.

pub fn to_payload(&self, nonce: Option<u32>) -> NodeIdentityPayload

Build the (unsigned) identity payload this node advertises, stamping nonce into option 5.

The one canonical builder, deliberately shared by both framings of a node identity: the Identity Request reply, which carries a request nonce and is authenticated by the enclosing unicast, and the standalone signed blob, which carries no nonce and is authenticated by a detached signature. They are different objects on the wire and the same statement about the node; the difference must not be able to drift into the contents.

Trait Implementations
