Module: Cborb::Decoding::Types::IntegerDecodable

Included in:
Array, ByteString, Integer, Map, NegativeInteger, Tag, TextString, UnassignedSimpleValue
Defined in:
lib/cborb/decoding/types/integer_decodable.rb

Overview

In CBOR, The process that decode some bytes as integer is popular. Thus, we modularize that.
