Enum Error 

#[non_exhaustive]
pub enum Error {
    InvalidOptions,
    LimitExceeded,
    InvalidPem,
    UnexpectedPemLabel,
    InvalidCertificate,
    TrailingData,
    InconsistentSignatureAlgorithm,
}

Typed local parsing failures, distinct from card status and transport errors.

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.

InvalidOptions

A zero parsing budget was supplied.

LimitExceeded

Encoded input or decoded DER exceeds the caller’s budget.

InvalidPem

PEM armor/base64 is invalid, or input contains extra text/blocks.

UnexpectedPemLabel

The PEM label is not CERTIFICATE.

InvalidCertificate

Input could not be decoded as an X.509 certificate.

TrailingData

Bytes follow the single DER certificate.

InconsistentSignatureAlgorithm

Legacy error retained for compatibility; parsing now preserves both identifiers.

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 Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
