Error for BER/DER parsers

Variants

BerTypeError

BER object does not have the expected type

BerValueError

BER object does not have the expected value

InvalidTag

InvalidClass

InvalidLength

ConstructExpected

DER object was expected to be constructed (and found to be primitive)

ConstructUnexpected

DER object was expected to be primitive (and found to be constructed)

IntegerTooLarge

BER integer is too large to fit in a native type. Use as_bigint()

BerMaxDepth

BER recursive parsing reached maximum depth (See MAX_RECURSION)

ObjectTooShort

When parsing a defined sequence, some items could not be found

DerConstraintFailed

A DER constraint failed (object may be using BER encoding?)

UnknownTag

Unsupported

Feature is not yet implemented

Custom(u32)

Custom error type left for parsers on top of this crate, so they can handle their custom errors

NomError(ErrorKind)

Error raised by the underlying nom parser

Trait Implementations

impl Debug for BerError

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

Formats the value using the given formatter.

impl Display for BerError

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

Formats the value using the given formatter.

impl Error for BerError

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

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<BerError> for Err<BerError>

fn from(e: BerError) -> Err<BerError>

Converts to this type from the input type.

impl<I> ParseError<I> for BerError

fn from_error_kind(_input: I, kind: ErrorKind) -> Self

creates an error from the input position and an ErrorKind

fn append(_input: I, kind: ErrorKind, _other: Self) -> Self

combines an existing error with a new one created from the input position and an ErrorKind. This is useful when backtracking through a parse tree, accumulating error context on the way

fn from_char(input: I, _: char) -> Self

creates an error from an input position and an expected character

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

combines two existing error. This function is used to compare errors generated in various branches of [alt]

fn add_context(_input: I, _ctx: &'static str, other: Self) -> Self

create a new error from an input position, a static string and an existing error. This is used mainly in the context combinator, to add user friendly information to errors when backtracking through a parse tree

impl PartialEq<BerError> for BerError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
