Struct Unspecified 

pub struct Unspecified;

A generic error type representing an unspecified failure in cryptographic operations.

In cryptographic contexts, it is often necessary to hide the specific reason for an operation’s failure to prevent leaking sensitive information to potential attackers. Unspecified serves this purpose by providing a simple, non-descriptive error type that can be used in situations where the cause of the failure should not be exposed.

Trait Implementations

impl Clone for Unspecified

fn clone(&self) -> Unspecified

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Unspecified

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

Formats the value using the given formatter.

impl Display for Unspecified

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

Writes “Unspecified” to the formatter.

impl Error for Unspecified

Available on crate feature std only.

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 Error for Unspecified

Available on crate feature embedded-io only.

fn kind(&self) -> ErrorKind

Get the kind of this error.

impl From<HexError> for Unspecified

Available on non-llvm_ir_check only.

fn from(_value: HexError) -> Self

Converts to this type from the input type.

impl From<Infallible> for Unspecified

fn from(_value: Infallible) -> Self

Converts to this type from the input type.

impl From<InvalidSize> for Unspecified

fn from(_value: InvalidSize) -> Self

Converts to this type from the input type.

impl<State: Poly1305State> From<Poly1305<State>> for Unspecified

Available on crate feature allow-non-fips only.

fn from(_value: Poly1305<State>) -> Self

Converts to this type from the input type.

impl From<StreamPoly1305> for Unspecified

Available on crate feature allow-non-fips only.

fn from(value: StreamPoly1305) -> Self

Converts to this type from the input type.

impl From<StreamPoly1305Aead> for Unspecified

Available on crate feature allow-non-fips only.

fn from(value: StreamPoly1305Aead) -> Self

Converts to this type from the input type.

impl Hash for Unspecified

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Unspecified

fn cmp(&self, other: &Unspecified) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Unspecified

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

impl PartialOrd for Unspecified

fn partial_cmp(&self, other: &Unspecified) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
