A list specifying general categories of TEE client error and its corresponding code in OP-TEE client library.

Variants

Generic

Non-specific cause.

AccessDenied

Access privileges are not sufficient.

Cancel

The operation was canceled.

AccessConflict

Concurrent accesses caused conflict.

ExcessData

Too much data for the requested operation was passed.

BadFormat

Input data was of invalid format.

BadParameters

Input parameters were invalid.

BadState

Operation is not valid in the current state.

ItemNotFound

The requested data item is not found.

NotImplemented

The requested operation should exist but is not yet implemented.

NotSupported

The requested operation is valid but is not supported in this implementation.

NoData

Expected data was missing.

OutOfMEmory

System ran out of resources.

Busy

The system is busy working on something else.

Communication

Communication with a remote party failed.

Security

A security fault was detected.

ShortBuffer

The supplied buffer is too short for the generated output.

ExternalCancel

Implementation defined error code.

TargetDead

Implementation defined error code: trusted Application has panicked during the operation.

Unknown

Unknown error.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for ErrorKind

impl PartialOrd<ErrorKind> for ErrorKind

fn partial_cmp(&self, other: &ErrorKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Copy for ErrorKind

impl PartialEq<ErrorKind> for ErrorKind

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

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

This method tests for !=.

impl Ord for ErrorKind

fn cmp(&self, other: &ErrorKind) -> Ordering

This method returns an Ordering between self and other.

default fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

default fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

default fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl From<ErrorKind> for Error

fn from(kind: ErrorKind) -> Error

Performs the conversion.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Hash for ErrorKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

default fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].
