Enum Error 

pub enum Error {
    InvalidHash,
    InvalidEccCurve,
    InvalidEccParameters,
    InvalidRsaParameters,
    KeyIsEmpty,
    OperationFailed,
    OutOfMemory,
    PermissionDenied,
}

The top-level error type for cryptographic operations.

Variants

InvalidHash

Hash algorithm is not supported in the context of use.

InvalidEccCurve

ECC curve is not supported in the context of use.

InvalidEccParameters

Invalid ECC public parameters.

InvalidRsaParameters

Invalid RSA public parameters.

KeyIsEmpty

A zero-length key was provided.

OperationFailed

A cryptographic operation failed.

OutOfMemory

Not enough memory available.

PermissionDenied

The provided HMAC does not match to the expected value.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

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