Struct IndexedSignature 

pub struct IndexedSignature {
    pub index: u32,
    pub prior_index: Option<u32>,
    pub sig: Vec<u8>,
}

A single indexed controller signature.

The index maps to the position in the key list (k field) of the signing key. Per the CESR spec, indexed signatures carry their key index in the derivation code.

Usage:

use auths_keri::IndexedSignature;
let sig = IndexedSignature { index: 0, prior_index: None, sig: vec![0u8; 64] };
assert_eq!(sig.index, 0);

Fields

index: u32

Index into the new key list k[] (which current key signed).

prior_index: Option<u32>

For a rotation signature, the index into the prior event’s next-key commitment list n[] that this signature reveals (CESR ondex).

Some(j) emits a dual-index (“Big”, 2A) siger; None emits the single-index code (A) with ondex == index — preserving the wire bytes of every single-index signer (inception, symmetric rotation).

sig: Vec<u8>

Raw signature bytes (64 bytes for Ed25519).
