Struct ergo_lib::wallet::derivation_path::DerivationPath

pub struct DerivationPath(_);

According to BIP-44 https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki and EIP-3 https://github.com/ergoplatform/eips/blob/master/eip-0003.md

Implementations

impl DerivationPath

pub fn new( acc: ChildIndexHardened, address_indices: Vec<ChildIndexNormal> ) -> Self

Create derivation path for a given account index (hardened) and address indices m / 44' / 429' / acc' / 0 / address[0] / address[1] / ... or m / 44' / 429' / acc' / 0 if address indices are empty change is always zero according to EIP-3

pub fn master_path() -> Self

Create root derivation path

pub fn depth(&self) -> usize

Returns the length of the derivation path

pub fn extend(&self, index: ChildIndex) -> DerivationPath

Extend the path with the given index. Returns this derivation path with added index.

pub fn next(&self) -> Result<DerivationPath, DerivationPathError>

Returns a new path with the last element of the deriviation path being increased, e.g. m/1/2 -> m/1/3 Returns an empty path error if the path is empty (master node for example)

pub fn ledger_bytes(&self) -> Vec<u8>

For 0x21 Sign Transaction command of Ergo Ledger App Protocol P2PK Sign (0x0D) instruction Sign calculated TX hash with private key for provided BIP44 path. Data:

Field Size (B) Description

BIP32 path length 1 Value: 0x02-0x0A (2-10). Number of path components

First derivation index 4 Big-endian. Value: 44’

Second derivation index 4 Big-endian. Value: 429’ (Ergo coin id)

Optional Third index 4 Big-endian. Any valid bip44 hardened value. … Optional Last index 4 Big-endian. Any valid bip44 value.

Trait Implementations

impl Clone for DerivationPath

fn clone(&self) -> DerivationPath

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DerivationPath

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

Formats the value using the given formatter.

impl Display for DerivationPath

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

Formats the value using the given formatter.

impl From<Box<[ChildIndex], Global>> for DerivationPath

fn from(original: Box<[ChildIndex]>) -> DerivationPath

Converts to this type from the input type.

impl FromStr for DerivationPath

type Err = DerivationPathError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq<DerivationPath> for DerivationPath

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

This method tests for self and other values to be equal, and is used by ==.

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

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