Struct UnspecifiedRandError 

pub struct UnspecifiedRandError;

An error with absolutely no details.

dup-crypto uses this unit type as the error type in most of its results because (a) usually the specific reasons for a failure are obvious or are not useful to know, and/or (b) providing more details about a failure might provide a dangerous side channel, and/or (c) it greatly simplifies the error handling logic.

Experience with using and implementing other crypto libraries like has shown that sophisticated error reporting facilities often cause significant bugs themselves, both within the crypto library and within users of the crypto library. This approach attempts to minimize complexity in the hopes of avoiding such problems. In some cases, this approach may be too extreme, and it may be important for an operation to provide some details about the cause of a failure. Users of dup-crypto are encouraged to report such cases so that they can be addressed individually.

Trait Implementations

impl Clone for UnspecifiedRandError

fn clone(&self) -> UnspecifiedRandError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnspecifiedRandError

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

Formats the value using the given formatter.

impl From<UnspecifiedRandError> for PrivateMessageError

fn from(_: UnspecifiedRandError) -> Self

Converts to this type from the input type.

impl PartialEq for UnspecifiedRandError

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