Trait Implementations

impl Debug for AttestationError

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

Formats the value using the given formatter.

impl Display for AttestationError

Human-readable messages for each AttestationError variant.

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

Formats the error as a single-line message.

impl Error for AttestationError

Allows AttestationError to be used as a standard error type.

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<Error> for AttestationError

Wraps I/O errors as AttestationError::Io.

fn from(err: Error) -> Self

Converts an I/O error into AttestationError::Io.
