Enum MasterKeyError 

pub enum MasterKeyError {
    AlreadyEstablished,
    Key(KeyError),
    Encryption(EncryptionError),
}

Why a CovenHandle master-key lifecycle call (initialize_master_key, import_master_key) failed.

Variants

AlreadyEstablished

initialize_master_key found a master key already established — custody unlock() returned Some. coven never generates over an existing key; the host imports or forgets it first.

Key(KeyError)

Encryption(EncryptionError)

Trait Implementations

impl Debug for MasterKeyError

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

Formats the value using the given formatter.

impl Display for MasterKeyError

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

Formats the value using the given formatter.

impl Error for MasterKeyError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
