Struct NodeAddr 

pub struct NodeAddr(/* private fields */);

16-byte node identifier derived from truncated SHA-256(pubkey).

The node_addr is the first 16 bytes of SHA-256(pubkey), providing 128 bits of collision resistance. Hashing the public key prevents grinding attacks that exploit secp256k1’s algebraic structure.

Implementations

impl NodeAddr

pub fn from_bytes(bytes: [u8; 16]) -> NodeAddr

Create a NodeAddr from a 16-byte array.

pub fn from_slice(slice: &[u8]) -> Result<NodeAddr, IdentityError>

Create a NodeAddr from a slice.

pub fn from_pubkey(pubkey: &XOnlyPublicKey) -> NodeAddr

Derive a NodeAddr from an x-only public key (npub).

Computes SHA-256(pubkey) and takes the first 16 bytes.

pub fn as_bytes(&self) -> &[u8; 16]

Return the raw bytes.

pub fn as_slice(&self) -> &[u8]

Return the bytes as a slice.

pub fn short_hex(&self) -> String

Return a short hex representation: first 4 bytes + “…”.

Trait Implementations

impl AsRef<[u8]> for NodeAddr

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for NodeAddr

fn clone(&self) -> NodeAddr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeAddr

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

Formats the value using the given formatter.

impl Display for NodeAddr

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

Formats the value using the given formatter.

impl Hash for NodeAddr

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

where __H: Hasher,

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 NodeAddr

fn cmp(&self, other: &NodeAddr) -> 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 NodeAddr

fn eq(&self, other: &NodeAddr) -> 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 NodeAddr

fn partial_cmp(&self, other: &NodeAddr) -> 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.
