Struct NonHardenedChildIndex

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

Expand description

A non-hardened index used in hierarchical deterministic wallet derivation paths.

Non-hardened indices allow public key derivation, enabling watch-only wallets to generate new addresses without having access to private keys. In BIP-44/ZIP-32 paths, the last two components (change and address_index) are typically non-hardened.

§Zcash Concept Relation

In Zcash HD wallet implementations:

Hardened indices are shown with an apostrophe (e.g., 44')
Non-hardened indices are shown without an apostrophe (e.g., 0 for external)

Non-hardened indices must be below 2^31 (0x80000000).

§Examples

// Create from a u32 value
let index = NonHardenedChildIndex::from(42u32);

// Convert back to u32 when needed
let value: u32 = index.into();
assert_eq!(value, 42);
