Struct ExternalKey 

pub struct ExternalKey {
    pub xpub: String,
    pub master_fingerprint: Vec<u8>,
    pub derivation_path: String,
}

This message represents an external key used for deriving and managing hierarchical deterministic (HD) wallet addresses according to BIP-86.

Fields

xpub: String

This field specifies the extended public key derived at depth 3 of the BIP-86 hierarchy (e.g., m/86’/0’/0’). This key serves as the parent key for deriving child public keys and addresses.

master_fingerprint: Vec<u8>

This field specifies the fingerprint of the master key, derived from the first 4 bytes of the hash160 of the master public key. It is used to identify the master key in BIP-86 derivation schemes.

derivation_path: String

This field specifies the extended BIP-86 derivation path used to derive a child key from the XPub. Starting from the base path of the XPub (e.g., m/86’/0’/0’), this path must contain exactly 5 components in total (e.g., m/86’/0’/0’/0/0), with the additional components defining specific child keys, such as individual addresses.

Trait Implementations

impl Clone for ExternalKey

fn clone(&self) -> ExternalKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExternalKey

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

Formats the value using the given formatter.

impl Default for ExternalKey

fn default() -> Self

Returns the “default value” for a type.

impl Message for ExternalKey

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ExternalKey

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