Enum HistoricalKeyPolicy 

pub enum HistoricalKeyPolicy {
    Reject,
    AcceptWithReceipt,
}

How to treat a producer key that is present in the DID document’s verificationMethod but no longer in assertionMethod — i.e. a key the producer rotated out but retained per the RFC-ACDP-0010 key-retention rule.

Variants

Reject

Strict 0.1.0 behavior: only assertionMethod keys verify. Every context signed by a rotated-out key fails.

AcceptWithReceipt

Accept a retained key only when a verified registry receipt attests (via key_fingerprint) that this exact key was the authorized one at publish time. Without a verified receipt the historical path never activates — fail closed. Default.

Trait Implementations

impl Clone for HistoricalKeyPolicy

fn clone(&self) -> HistoricalKeyPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HistoricalKeyPolicy

impl Debug for HistoricalKeyPolicy

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

Formats the value using the given formatter.

impl Default for HistoricalKeyPolicy

fn default() -> HistoricalKeyPolicy

Returns the “default value” for a type.

impl Eq for HistoricalKeyPolicy

impl PartialEq for HistoricalKeyPolicy

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