Enum KeyOrigin 

pub enum KeyOrigin {
    DeviceKey,
    ProcessingKey,
    KeyDbDerived,
    KeyDb,
    KeyDbUnitKeys,
    ExternalUk,
}

How AACS keys were resolved. Variants are ordered root-of-trust → per-disc-leaf, matching the resolver’s path-try order: the resolver attempts derivation from the strongest input it has first and falls back toward pre-computed per-disc material.

Variants

DeviceKey

MKB + device keys → subset-difference tree → VUK

ProcessingKey

MKB + processing keys → media key → VUK

KeyDbDerived

Media key + Volume ID from KEYDB → derived VUK

KeyDb

VUK found directly in KEYDB by disc hash

KeyDbUnitKeys

Pre-decrypted unit keys taken directly from KEYDB by disc hash. No VUK present in the entry — AacsState::vuk is None.

ExternalUk

Unit key supplied directly by the caller (the external Unit Key path). No keydb, no derivation — AacsState::vuk is None.

Implementations

impl KeyOrigin

pub fn name(&self) -> &'static str

Trait Implementations

impl Clone for KeyOrigin

fn clone(&self) -> KeyOrigin

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for KeyOrigin

impl Debug for KeyOrigin

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

Formats the value using the given formatter.

impl PartialEq for KeyOrigin

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