Struct ExpandedKey 

pub struct ExpandedKey {
    pub idx: u8,
    pub origin_path: OriginPath,
    pub use_site_path: UseSitePath,
    pub fingerprint: Option<[u8; 4]>,
    pub xpub: Option<[u8; 65]>,
}

Fully-resolved per-@N key record produced by expand_per_at_n.

Each field is populated via the canonical-fill / per-@N override composition rules (spec v0.13 §5.3 + §6.3, “Option A”):

• origin_path: OriginPathOverrides[idx] if present, else path_decl resolved per the Shared / Divergent variant.
• use_site_path: UseSitePathOverrides[idx] if present, else Descriptor::use_site_path (the descriptor-level baseline).
• fingerprint: Fingerprints[idx] if present, else None.
• xpub: Pubkeys[idx] if present, else None.

Fields

idx: u8

Placeholder index @N; equals position in the returned Vec.

origin_path: OriginPath

Resolved origin path (per-@N override or path_decl baseline).

use_site_path: UseSitePath

Resolved use-site path (per-@N override or descriptor baseline).

fingerprint: Option<[u8; 4]>

4-byte master fingerprint, if a Fingerprints entry is present.

xpub: Option<[u8; 65]>

65-byte xpub (32 chain-code || 33 compressed pubkey), if a Pubkeys entry is present.

Trait Implementations

impl Clone for ExpandedKey

fn clone(&self) -> ExpandedKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpandedKey

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

Formats the value using the given formatter.

impl PartialEq for ExpandedKey

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