Errors for this crate.

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.

UnterminatedBytes

The bytes finish before the last octet.

RedundantBytes

The bytes include some redundant octet(s). (‘ASN.1’ does not allow such bytes.)

OverFlow

Over flow is occurred to parse bytes as a number.

IndefiniteLength

‘Indefinite length’ is used where not allowed. (It is only for BER of some type, but not for DER, nor for CER.)

BadEoc

The contents of ‘EOC’ of the ‘Indefinite Length BER’ must be empty.

ExtraContentsOctet

The contents include (an) invalid octet(s) at the end.

UnmatchedId

The identifier does not match to that of data type when deserialized.

InvalidUtf8

Invarid as UTF-8.

InvalidDerBooleanContents

The contents of DER BOOLEAN must be 0x00 or 0xFF.

InvalidKeyValuePair

The key-value pair is invalid.

Io(Error)

IO Error for serialization/deserialization.

Note that this error cannot be compared with others. PartialEq::eq always returns false for this error.

Anyhow(Error)

Wrapper of anyhow::Error.

Note that this error cannot be compared with others. PartialEq::eq always returns false for this error.

Implementations

impl Error

pub fn into_anyhow(self) -> Error

Consumes self, converting it into an anyhow::Error.

If self matches Error::Anyhow, returns the inner value; otherwise, wraps self and returns.

pub fn as_anyhow(&self) -> Option<&Error>

Returns a reference to the inner anyhow::Error if self is Error::Anyhow; otherwise, returns None.

pub fn context<C>(self, context: C) -> Self

where C: Display + Send + Sync + 'static,

Consumes self, wrapping it with context.

pub fn root_cause(&self) -> &Self

If self matches Error::Anyhow, returns a reference to the first Self type error in the chain; otherwise, returns self.

Trait Implementations

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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 From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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