Enum ProviderError 

pub enum ProviderError {
    Unsupported {
        provider: CryptoProviderId,
        op: &'static str,
        algorithm: &'static str,
    },
    PolicyDenied {
        op: &'static str,
        reason: &'static str,
    },
    CryptoFailed {
        provider: CryptoProviderId,
        op: &'static str,
        algorithm: &'static str,
        reason: &'static str,
    },
    Backend(BackendError),
}

Errors raised before or inside a provider operation.

Variants

Unsupported

The selected provider does not implement this operation/algorithm.

Fields

provider: CryptoProviderId

Provider that rejected the operation.

op: &'static str

Operation name.

algorithm: &'static str

Algorithm name.

PolicyDenied

Policy or custody labels forbid the requested provider.

Fields

op: &'static str

Operation name.

reason: &'static str

Stable reason.

CryptoFailed

A software-custody crypto or record operation failed: a malformed custody record, wrong key material, or a decapsulation/verification/seal failure. The message is opaque: it never contains seed, key, plaintext, signature, or shared-secret bytes (no decrypt oracle).

Fields

provider: CryptoProviderId

Provider that failed.

op: &'static str

Operation name.

algorithm: &'static str

Algorithm name.

reason: &'static str

Stable, secret-free reason token.

Backend(BackendError)

Concrete backend error.

Trait Implementations

impl Debug for ProviderError

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

Formats the value using the given formatter.

impl Display for ProviderError

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

Formats the value using the given formatter.

impl Error for ProviderError

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.

impl From<BackendError> for ProviderError

fn from(source: BackendError) -> Self

Converts to this type from the input type.

impl From<ProviderError> for ManagerError

fn from(source: ProviderError) -> Self

Converts to this type from the input type.
