Summary
Replaces two
IndexOfAny(new char[] { ... })calls — which allocate achar[]on every invocation — with hoisted staticSearchValues<char>and span-basedIndexOfAny(.NET 10 idiom). Byte-identical result, no per-call allocation.Changes
LogsViewModel.Csv(CSV export, called per-field × per-row) —s.IndexOfAny(new[]{',','"','\n','\r'})→ staticCsvSpecials = SearchValues.Create(",\"\n\r")+s.AsSpan().IndexOfAny(CsvSpecials).UpdateService.ParseVersion—s.IndexOfAny(new[]{'-','+',' '})→ staticVersionSuffixSeparators+ span IndexOfAny.Why byte-identical
SearchValues<char>.IndexOfAnyover a span returns the same first-match index asstring.IndexOfAny(char[]); only the allocation is removed.Verification
refactor:→ no release.
