Struct optee_teec::Error

pub struct Error { /* fields omitted */ }

The error type for TEE operations of Context and Session.

Implementations

impl Error

pub fn new(kind: ErrorKind) -> Error

pub fn from_raw_error(code: u32) -> Error

Creates a new instance of an Error from a particular TEE error code.

Examples

use optee_teec;

let error = optee_teec::Error::from_raw_error(0xFFFF000F);
assert_eq!(error.kind(), optee_teec::ErrorKind::Security);

pub fn kind(&self) -> ErrorKind

Returns the corresponding ErrorKind for this error.

Examples

use optee_teec;

let error = optee_teec::Error::new(optee_teec::ErrorKind::Security);

pub fn raw_code(&self) -> u32

Returns raw code of this error.

pub fn message(&self) -> &str

Returns corresponding error message of this error.

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<ErrorKind> for Error

fn from(kind: ErrorKind) -> Error

Performs the conversion.
