pub fn children_from(&self, cn: ChildNumber) -> DerivationPathIterator<'_>

Get an Iterator over the children of this DerivationPath starting with the given ChildNumber.

pub fn normal_children(&self) -> DerivationPathIterator<'_>

Get an Iterator over the unhardened children of this DerivationPath.

pub fn hardened_children(&self) -> DerivationPathIterator<'_>

Get an Iterator over the hardened children of this DerivationPath.

pub fn extend<T>(&self, path: T) -> DerivationPath

where T: AsRef<[ChildNumber]>,

Concatenate self with path and return the resulting new path.

use bitcoin::util::bip32::{DerivationPath, ChildNumber};

impl Ord for DerivationPath

fn cmp(&self, other: &DerivationPath) -> Ordering

This method returns an Ordering between self and other.

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.
