Struct eosio::UnsignedInt

pub struct UnsignedInt(_);

Variable Length Unsigned Integer. This provides more efficient serialization of 32-bit unsigned int. It serialuzes a 32-bit unsigned integer in as few bytes as possible. UnsignedInt is unsigned and uses VLQ or Base-128 encoding https://github.com/EOSIO/eosio.cdt/blob/4985359a30da1f883418b7133593f835927b8046/libraries/eosiolib/core/eosio/varint.hpp#L15-L237
