Struct DerivationPath 

pub struct DerivationPath { /* private fields */ }

BIP32 derivation path.

Example

use rustywallet_hd::DerivationPath;

// Parse a BIP44 Bitcoin path
let path = DerivationPath::parse("m/44'/0'/0'/0/0").unwrap();
assert_eq!(path.to_string(), "m/44'/0'/0'/0/0");

// Use helper for BIP44 Bitcoin
let btc_path = DerivationPath::bip44_bitcoin(0, 0, 0);
assert_eq!(btc_path.to_string(), "m/44'/0'/0'/0/0");

Implementations

impl DerivationPath

pub fn master() -> Self

Create an empty path (master key).

pub fn parse(path: &str) -> Result<Self, HdError>

Parse a derivation path from string.

Supports both ' and h notation for hardened derivation.

pub fn bip44_bitcoin(account: u32, change: u32, index: u32) -> Self

Create BIP44 path for Bitcoin: m/44’/0’/account’/change/index

pub fn bip44_ethereum(account: u32, index: u32) -> Self

Create BIP44 path for Ethereum: m/44’/60’/account’/0/index

pub fn components(&self) -> &[ChildNumber]

Get path components.

pub fn has_hardened(&self) -> bool

Check if path contains any hardened derivation.

pub fn depth(&self) -> u8

Get the depth (number of components).

pub fn child(&self, child: ChildNumber) -> Self

Append a child number to the path.

Trait Implementations

impl Clone for DerivationPath

fn clone(&self) -> DerivationPath

Returns a duplicate 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 FromStr for DerivationPath

type Err = HdError

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 for DerivationPath

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