Errors that can occur when talking to a TPM device.

Display renders only the variant name as lowercase space-separated words (e.g. UnexpectedEof becomes unexpected eof).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AlreadyBorrowed

The TPM device is already mutably borrowed.

CapabilityMissing(TpmCap)

The requested capability is not available from the TPM.

Interrupted

The operation was interrupted by the caller.

InvalidCc(TpmCc)

An invalid command code was used.

InvalidResponse

The TPM returned an invalid or malformed response.

Io(Error)

An I/O error occurred when accessing the TPM device.

Marshal(TpmError)

Marshaling a TPM protocol encoded object failed.

NotAvailable

No TPM device is available.

PcrBanksNotAvailable

No PCR banks are available on the TPM.

PcrBankSelectionMismatch

The PCR selection masks differ between active banks.

ResponseMismatch(TpmCc)

The TPM response did not match the expected command code.

Timeout

The TPM command timed out.

TpmRc(TpmRc)

The TPM returned an error code.

TrailingData

Trailing data after the response.

Unmarshal(TpmError)

Unmarshaling a TPM protocol encoded object failed.

UnexpectedEof

An unexpected end-of-file was encountered.

UnsupportedAlgorithm(TpmAlgId)

The requested algorithm is not supported.

Trait Implementations

impl AsRef<str> for TpmDeviceError

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Debug for TpmDeviceError

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

Formats the value using the given formatter.

impl Display for TpmDeviceError

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

Formats the value using the given formatter.

impl Eq for TpmDeviceError

impl Error for TpmDeviceError

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<Errno> for TpmDeviceError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for TpmDeviceError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<TpmRc> for TpmDeviceError

fn from(rc: TpmRc) -> Self

Converts to this type from the input type.

impl PartialEq for TpmDeviceError

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
