Struct eosio::SignedInt

pub struct SignedInt(_);

Variable Length Signed Integer. This provides more efficient serialization of 32-bit signed int. It serializes a 32-bit signed integer in as few bytes as possible. SignedInt is signed and uses Zig-Zag encoding https://github.com/EOSIO/eosio.cdt/blob/4985359a30da1f883418b7133593f835927b8046/libraries/eosiolib/core/eosio/varint.hpp#L239-L465
