Struct InMemoryDekShredder 

pub struct InMemoryDekShredder { /* private fields */ }

In-memory DekShredder — deterministic Ed25519-style placeholder attestation for tests and the Tier-0 harness. All paths emit RuntimeSignatureClass::Ed25519 regardless of compliance tier.

Implementations

impl InMemoryDekShredder

pub fn new() -> Self

Construct an empty shredder — no DEKs registered.

pub fn register(&mut self, dek_id: DekId)

Register a DEK the observer will later be asked to shred. The shredder does not store plaintext key material — just the id.

pub fn is_shredded(&self, dek_id: &DekId) -> bool

Check whether a given DEK id was shredded.

Trait Implementations

impl Debug for InMemoryDekShredder

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

Formats the value using the given formatter.

impl Default for InMemoryDekShredder

fn default() -> InMemoryDekShredder

Returns the “default value” for a type.

impl DekShredder for InMemoryDekShredder

fn shred(&mut self, dek_id: DekId) -> Result<DekShredAttestation, DekShredError>

Drop plaintext DEK material for dek_id and return an attestation payload the observer folds into the UserErasureCompleted.attestation_bytes field. See the trait- level idempotency contract for replay semantics.

fn shred_with_regions( &mut self, dek_id: DekId, shred_tick: Tick, ) -> Result<ShredResult, DekShredError>

Multi-region 2PC variant. Real backends override this to drive a multi-KMS / multi-region shred and return the per-region progress entries so the cascade observer can emit matching PerRegionErasureProgress events.
