Struct TestCustody 

pub struct TestCustody { /* private fields */ }

In-memory MasterKeyCustody for tests, with a switch to force persist to fail. The switch models a device whose keyring is momentarily unwritable, so a test can drive a key adoption into its failure path and then clear the switch to prove the retry converges. Stores the serialized form (like the real Keyring preset), so stored_key reflects exactly what a caller wrote.

Implementations

impl TestCustody

pub fn set_initial_key(&self, key: [u8; 32])

pub fn stored_key(&self) -> Option<String>

pub fn fail_writes(&self)

Make the next and every subsequent persist fail until cleared.

pub fn allow_writes(&self)

Let persist succeed again.

Trait Implementations

impl Clone for TestCustody

fn clone(&self) -> TestCustody

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for TestCustody

fn default() -> TestCustody

Returns the “default value” for a type.

impl MasterKeyCustody for TestCustody

fn unlock(&self) -> Result<Option<MasterKeyring>, KeyError>

The store’s master keyring for this session. Ok(None) means the store has never had one established (a fresh store before create/join) — distinct from a failure to produce one (wrong passphrase, unreadable backing store), which is Err.

fn persist(&self, keyring: &MasterKeyring) -> Result<(), KeyError>

Protect and store keyring, replacing whatever is stored. Serves both establishment (create/join/restore) and rotation re-protection (member removal, the per-cycle refresh adoption). Idempotent.

fn forget(&self) -> Result<(), KeyError>

Remove the stored keyring. Ok when nothing was stored.
