Enum DrbgError 

pub enum DrbgError {
    RequestTooLarge,
    ReseedRequired,
    EntropyUnavailable,
    EntropyHealthFailed,
}

Errors surfaced by deterministic random bit generators inside the crypto module.

Variants

RequestTooLarge

Generated output exceeded the maximum request length.

ReseedRequired

Generator must be reseeded with fresh entropy before more output is produced.

EntropyUnavailable

Underlying entropy source failed.

EntropyHealthFailed

Entropy health check failed (weak or repeated seed material).

Trait Implementations

impl Clone for DrbgError

fn clone(&self) -> DrbgError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DrbgError

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

Formats the value using the given formatter.

impl Display for DrbgError

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

Formats the value using the given formatter.

impl Error for DrbgError

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<DrbgError> for CryptoError

fn from(err: DrbgError) -> Self

Converts to this type from the input type.

impl From<Error> for DrbgError

fn from(value: InnerError) -> Self

Converts to this type from the input type.

impl PartialEq for DrbgError

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