decodeAsn1VarUInt

fun ByteArray.decodeAsn1VarUInt(): Pair<UInt, ByteArray>(source)

Decodes an UInt from bytes using varint encoding as used within ASN.1: groups of seven bits are encoded into a byte, while the highest bit indicates if more bytes are to come. Trailing bytes are ignored.

Return

the decoded UInt and the underlying varint-encoded bytes as ByteArray

Throws

if the number is larger than UInt.MAX_VALUE

fun Source.decodeAsn1VarUInt(): Pair<UInt, ByteArray>(source)

Decodes an ASN.1 unsigned varint to an UInt, copying all bytes from the source into a ByteArray.

Return

the decoded UInt and the underlying varint-encoded bytes as ByteArray

Throws

if the number is larger than UInt.MAX_VALUE
