5525-5528: LGTM! Consider using strconv.FormatUint for better performanceThe test case for maximum uint value is well-designed and helps prevent regression of the overflow bug. However, fmt.Sprintf can be replaced with strconv.FormatUint for better performance.

799-799: LGTM! Good fix for the uint overflow issue.Changing the bit size from 32 to 0 is the correct solution. This allows
strconv.ParseUintto use the platform's native uint size (32 bits on 32-bit systems, 64 bits on 64-bit systems), preventing overflow when parsing large uint values.
Description
genericParseTypeparsing a largeuintleads to overflow. When parsinguintstring, thebitSizeofstrconv.ParseUintshould be0instead of32.Checklist
