Struct KeyRejected

pub struct KeyRejected(/* private fields */);

An error parsing or validating a key.

The Display implementation and <KeyRejected as Error>::description() will return a string that will help you better understand why a key was rejected change which errors are reported in which situations while minimizing the likelihood that any applications will be broken.

Here is an incomplete list of reasons a key may be unsupported:

• Invalid or Inconsistent Components: A component of the key has an invalid value, or the mathematical relationship between two (or more) components required for a valid key does not hold.

• The encoding of the key is invalid. Perhaps the key isn’t in the correct format; e.g. it may be Base64 (“PEM”) encoded, in which case the Base64 encoding needs to be undone first.

• The encoding includes a versioning mechanism and that mechanism indicates that the key is encoded in a version of the encoding that isn’t supported. This might happen for multi-prime RSA keys (keys with more than two private prime factors), which aren’t supported, for example.

• Too small or too Large: One of the primary components of the key is too small or two large. Too-small keys are rejected for security reasons. Some unnecessarily large keys are rejected for performance reasons.

• Wrong algorithm: The key is not valid for the algorithm in which it was being used.

• Unexpected errors: Report this as a bug.

Implementations

impl KeyRejected

pub fn description_(&self) -> &'static str

The value returned from <Self as std::error::Error>::description()

Trait Implementations

impl Clone for KeyRejected

fn clone(&self) -> KeyRejected

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyRejected

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

Formats the value using the given formatter.

impl Display for KeyRejected

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

Formats the value using the given formatter.

impl Error for KeyRejected

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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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<()> for KeyRejected

fn from((): ()) -> Self

Converts to this type from the input type.

impl From<KeyRejected> for Unspecified

fn from(_: KeyRejected) -> Self

Converts to this type from the input type.

impl From<TryFromIntError> for KeyRejected

fn from(_: TryFromIntError) -> Self

Converts to this type from the input type.

impl From<Unspecified> for KeyRejected

fn from(_: Unspecified) -> Self

Converts to this type from the input type.

impl PartialEq for KeyRejected

fn eq(&self, other: &KeyRejected) -> 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 Copy for KeyRejected
