Why a parse stopped.

Malformed input is a statement about the bytes. A spent budget is a statement about this run, and the two must not be confused.

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.

UnexpectedEnd

The element claims more bytes than the enclosing element has left.

MalformedTag

A tag number was encoded with a leading zero byte, or does not end.

TagTooLarge

A tag number too large to represent.

LengthNotMinimal

A definite length was not encoded in the fewest bytes DER allows.

LengthTooLarge

A length too large to represent as an offset on this target.

OffsetTooLarge

An offset that would not fit, given where this window starts.

IndefiniteLengthNotAllowed

An indefinite length where the schema requires a definite one.

UnterminatedContents

An indefinite-length element that never reached its end-of-contents.

MalformedEndOfContents

End-of-contents was encoded with a non-zero length.

WrongConstruction

A primitive element encoded as constructed, or the reverse.

UnexpectedTag

The element is not the one the schema asked for.

IntegerNotMinimal

An integer with a redundant leading 0x00 or 0xff byte.

IntegerEmpty

An integer with no content bytes at all.

MalformedOid

An object identifier that is empty, ends mid-arc, or pads an arc.

MalformedBitString

A bit string with no count of padding bits, a count above seven, or, under DER, padding bits that are not zero.

MalformedBoolean

A boolean of the wrong length, or, under DER, a true that is not 0xff.

MalformedNull

A null with contents.

MalformedReal

A real whose octets are not a value of the type: a reserved base or number representation, a part written in more octets than it needs, or a mantissa the normalization forbids.

LimitExceeded(Limit)

The work this input asks for is more than the caller allowed.

Distinct from every code above on purpose: nothing is wrong with the input, and reporting it as malformed would tell somebody their document is broken when the truth is that this device declined to finish.

AllocatorExhausted

The allocator could not supply storage, independently of configured limits.

CapacityOverflow

A requested allocation’s capacity cannot be represented on this target.
