Struct zip32::ChildIndex

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

A child index for a derived key.

Only hardened derivation is supported.

Implementations

impl ChildIndex

pub fn from_index(i: u32) -> Option<Self>

Parses the given ZIP 32 child index.

Returns None if the hardened bit is not set.

pub const fn hardened(value: u32) -> Self

Constructs a hardened ChildIndex from the given value.

Panics

Panics if value >= (1 << 31).

pub fn index(&self) -> u32

Returns the index as a 32-bit integer, including the hardened bit.

Trait Implementations

impl Clone for ChildIndex

fn clone(&self) -> ChildIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ConstantTimeEq for ChildIndex

fn ct_eq(&self, other: &Self) -> Choice

Determine if two items are equal.

fn ct_ne(&self, other: &Self) -> Choice

Determine if two items are NOT equal.

impl Debug for ChildIndex

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

Formats the value using the given formatter.

impl From<AccountId> for ChildIndex

fn from(id: AccountId) -> Self

Converts to this type from the input type.

impl PartialEq for ChildIndex

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