Description

The Sway language does not currently support any mathematical operations on a b256. Fuel core v0.19 support will add the WQOP op code for add, sub, shifts, etc but until then an increment by u64 function may be implemented.

https://github.com/FuelLabs/fuel-specs/blob/master/src/fuel-vm/instruction-set.md#wqop-misc-256-bit-integer-operations

Motivation

This functionality is required to optimize storage read/write operations.
