TPM frame marshaling and unmarshaling error type.

Every variant carries the byte offset from the start of the parsed buffer along with the diagnostic counts relevant to that failure.

Variants

BufferOverflow

Trying to marshal more bytes than buffer has space. This is unexpected situation, and should be considered possible bug in the crate itself.

Fields

offset: usize

Byte offset from the start of the buffer.

needed: usize

Required byte count.

available: usize

Available byte count.

IntegerTooLarge

Integer overflow while converting to an integer of a different size.

Fields

offset: usize

Byte offset from the start of the buffer.

value: u64

Raw value that did not fit.

InvalidBoolean

Boolean value was expected but the value is neither 0 nor 1.

Fields

offset: usize

Byte offset from the start of the buffer.

value: u64

Raw value encountered.

InvalidCc

Non-existent command code encountered.

Fields

offset: usize

Byte offset from the start of the buffer.

value: u64

Raw command code encountered.

InvalidMagicNumber

A TpmsAttest instance does not begin with the TPM_GENERATED_VALUE magic.

Fields

offset: usize

Byte offset from the start of the buffer.

value: u64

Raw magic value encountered.

InvalidRc

Invalid TPM response code encountered.

Fields

offset: usize

Byte offset from the start of the buffer.

value: u64

Raw response code encountered.

InvalidTag

Tag is neither Sessions nor NoSessions.

Fields

offset: usize

Byte offset from the start of the buffer.

value: u64

Raw tag encountered.

TooManyBytes

Buffer contains more bytes than allowed by the TCG specifications.

Fields

offset: usize

Byte offset from the start of the buffer.

limit: usize

Maximum allowed byte count.

actual: usize

Actual byte count.

TooManyItems

List contains more items than allowed by the TCG specifications.

Fields

offset: usize

Byte offset from the start of the buffer.

limit: usize

Maximum allowed item count.

actual: usize

Actual item count.

TrailingData

Trailing data left after unmarshaling.

Fields

offset: usize

Byte offset from the start of the buffer.

actual: usize

Trailing byte or item count.

UnexpectedEnd

Run out of bytes while unmarshaling.

Fields

offset: usize

Byte offset from the start of the buffer.

needed: usize

Required byte count.

available: usize

Available byte count.

VariantNotAvailable

The variant accessed is not available.

Fields

offset: usize

Byte offset from the start of the buffer.

value: u64

Raw value encountered.

Implementations

impl TpmError

pub const fn kind(self) -> &'static str

Returns the stable machine-readable name of the error variant.

Trait Implementations

impl Clone for TpmError

fn clone(&self) -> TpmError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TpmError

impl Debug for TpmError

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

Formats the value using the given formatter.

impl Display for TpmError

Renders TpmError as its bare variant name in lowercase, space-separated words (e.g. BufferOverflow becomes buffer overflow).

As the lowest-level crate in the stack, errors expose only the variant name here, derived from the stable kind discriminant. Callers read the structured fields directly and decide how to present the diagnostic detail.

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

Formats the value using the given formatter.

impl Eq for TpmError

impl Error for TpmError

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 PartialEq for TpmError

fn eq(&self, other: &TpmError) -> 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.
