Enum CryptoError 

#[non_exhaustive]
pub enum CryptoError {
    InvalidSignature,
    InvalidKeyLength {
        expected: usize,
        actual: usize,
    },
    InvalidPrivateKey(String),
    OperationFailed(String),
    UnsupportedTarget,
}

Error type for cryptographic operations.

Usage:

match result {
    Err(CryptoError::InvalidSignature) => { /* signature did not verify */ }
    Err(CryptoError::UnsupportedTarget) => { /* not available on this platform */ }
    Err(CryptoError::OperationFailed(msg)) => { /* backend error */ }
    Ok(()) => { /* success */ }
}

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.

InvalidSignature

InvalidKeyLength

Fields

expected: usize

Trait Implementations

impl AuthsErrorInfo for CryptoError

fn error_code(&self) -> &'static str

Returns a unique error code string for this error variant.

fn suggestion(&self) -> Option<&'static str>

Returns an optional actionable suggestion for resolving the error.

impl Clone for CryptoError

fn clone(&self) -> CryptoError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CryptoError

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

Formats the value using the given formatter.

impl Display for CryptoError

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

Formats the value using the given formatter.

impl Error for CryptoError

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.
