Error for BER/DER parsers

Variants

BerTypeError

BER object does not have the expected type

BerValueError

BER object does not have the expected value

InvalidTagInvalidClassInvalidLengthConstructExpected

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?)

UnknownTagUnsupported

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 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: &BerError) -> bool

This method tests for !=.

impl Debug for BerError

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

Formats the value using the given formatter.

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
