Enum PlatformError 

pub enum PlatformError {
    KeyNotFound,
    WrongKeyType {
        expected: KeyType,
        actual: KeyType,
    },
    StorageError(String),
    AttestationError(String),
    PushError(String),
    CustodyError(String),
}

Errors returned by platform abstraction trait implementations.

Each variant covers a distinct failure mode across the four platform traits (KeyCustody, DeviceAttestation, Push, Storage). See ADR-006 for the full platform adapter design.

Variants

KeyNotFound

The specified key handle does not exist or has been destroyed.

WrongKeyType

An operation was attempted with a key of the wrong type.

For example, calling sign with an X25519 key handle, or calling dh_agree with an Ed25519 key handle.

Fields

expected: KeyType

The key type the operation requires.

actual: KeyType

The key type that was actually provided.

StorageError(String)

A storage operation failed.

AttestationError(String)

A device attestation operation failed.

PushError(String)

A push notification operation failed.

CustodyError(String)

A key custody operation failed for reasons other than key-not-found or wrong-key-type.

Trait Implementations

impl Debug for PlatformError

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

Formats the value using the given formatter.

impl Display for PlatformError

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

Formats the value using the given formatter.

impl Error for PlatformError

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.
