Module set_of 

ASN.1 SET OF support.

Ordering Notes

Some DER serializer implementations fail to properly sort elements of a SET OF. This is technically non-canonical, but occurs frequently enough that most DER decoders tolerate it.

When decoding with EncodingRules::Der, this implementation sorts the elements of SET OF at decode-time to ensure reserializations are canonical.

Structs

SetOfIter

Iterator over the elements of an [SetOf].

SetOfVec

ASN.1 SET OF backed by a Vec.

Functions

check_der_ordering 🔒

Ensure set elements are lexicographically ordered using DerOrd.

check_duplicate 🔒

Check if the given item is a duplicate, given an iterator over sorted items (which we can short-circuit once we hit Ordering::Less.

der_sort 🔒

Sort a mut slice according to its DerOrd, returning any errors which might occur during the comparison.
