Enum Error 

#[non_exhaustive]
pub enum Error {

Available on non-crate feature webpki only.

Errors that can be produced when parsing a certificate or validating a signature.

More errors may be added in the future.

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.

UnsupportedCertVersion

Version is not valid. Without the legacy-certificates feature, only X.509 v3 certificates are supported. If the legacy-certificates feature is enabled, v1 and v2 certificates are also supported.

UnsupportedSignatureAlgorithm

Signature algorithm unsupported

UnsupportedSignatureAlgorithmForPublicKey

Signature algorithm isn’t valid for the public key

InvalidSignatureForPublicKey

Signature forged!

SignatureAlgorithmMismatch

Signature algorithms don’t match

BadDER

Invalid DER. This will also result if the legacy-certificates feature is disabled, but one of the (obsolete and virtually unused) subjectUniqueId and issuerUniqueId fields are present. Even if the legacy-certificates feature is enabled, these fields will not appear in the parsed certificate.

BadDERTime

Invalid DER time

CertNotValidYet

Certificate isn’t valid yet

CertExpired

Certificate has expired

InvalidCertValidity

Certificate expired before beginning to be valid

UnknownIssuer

The issuer is not known.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Hash for Error

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 PartialEq for Error

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