Enum BackendError 

#[non_exhaustive]
pub enum BackendError {
    KeyImport(String<OTHER_DETAIL_MAX>),
    KeyGen(String<OTHER_DETAIL_MAX>),
    Crypto(String<OTHER_DETAIL_MAX>),
    Rng(String<OTHER_DETAIL_MAX>),
    Unsupported(String<OTHER_DETAIL_MAX>),
}

Coarse error surface returned by every backend trait method (PDD §3.3/§8). Carries an opaque detail so software and HSM/PKCS#11 backends can attach context without leaking key material.

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.

KeyImport(String<OTHER_DETAIL_MAX>)

KeyGen(String<OTHER_DETAIL_MAX>)

Crypto(String<OTHER_DETAIL_MAX>)

Rng(String<OTHER_DETAIL_MAX>)

Unsupported(String<OTHER_DETAIL_MAX>)

Trait Implementations

impl Debug for BackendError

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

Formats the value using the given formatter.

impl Display for BackendError

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

Formats the value using the given formatter.

impl Error for BackendError

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<BackendError> for ScllError

fn from(source: BackendError) -> Self

Converts to this type from the input type.
