* Add benchmarks for potentially optimizable RuneExtensions * Add new RuneExtensions.DecodeSurrogatePair benchmark implementation Avoids intermediate heap array allocations which is especially nice when the rune is not surrogate pair because then array heap allocations are completely avoided. * Enable nullable reference types in RuneExtensions * Make RuneExtensions.MaxUnicodeCodePoint readonly Makes sure no one can accidentally change the value. Ideally would be const value. * Optimize RuneExtensions.DecodeSurrogatePair * Remove duplicate Rune.GetUnicodeCategory call * Add new RuneExtensions.IsSurrogatePair benchmark implementation Avoids intermediate heap allocations by using stack allocated buffer. * Optimize RuneExtensions.IsSurrogatePair * Add RuneExtensions.GetEncodingLength tests * Optimize RuneExtensions.GetEncodingLength * Optimize RuneExtensions.Encode * Print encoding name in benchmark results * Rename variable to better match return description * Add RuneExtensions.EncodeSurrogatePair benchmark --------- Co-authored-by: Tig <[email protected]>
* Replace Region.Contains LINQ lambdas with foreach loop Removes the lambda func allocations caused by captured outer variables. * Replace LineCanvas.Has LINQ lambda with foreach loop * Fix LineCanvas.GetMap intersects array nullability It should be enough to add null-forgiving operator somewhere in the LINQ query to make the final result non-null. No need to shove the nullability further down the line to complicate things. :) * Replace LineCanvas.All LINQ lambda with foreach loop * Replace Region.Intersect LINQ lambdas and list allocation with foreach loop and rented array * Use stackalloc buffer in Region.Intersect when max 8 rectangles * Fix LineCanvas.GetCellMap intersects array nullability * Remove leftover LineCanvas.GetRuneForIntersects null-conditional operators * Remove leftover IntersectionRuneResolver.GetRuneForIntersects null-conditional operators * PosAlign.CalculateMinDimension: calculate sum during loop No need to first put the dimensions in a list and then sum the list when you can just add to sum while looping through dimensions. * PosAlign.CalculateMinDimension: Remove intermediate list and related filter func allocation * TextFormatter.GetRuneWidth: Remove intermediate list and related sum func allocation * ReadOnlySpan refactor preparation for GetCellMap rewrite * LineCanvas.GetCellMap: Reuse intersection list outside nested loops GetCellMap would not benefit much from array pool because IntersectionDefinition is not struct. This change eliminates majority of the rest of Func<,> allocations. As a bonus IntersectionDefinition[] allocations dropped nicely. * Refactor local method UseRounded * Wrap too long list of method parameters * Region: Consistent location for #nullable enable --------- Co-authored-by: Tig <[email protected]>
* Fixed gui-cs#3905, gui-cs#3918 * Tweaked Generic * Label code cleanup * Clean up. * Clean up. * Clean up2.
* fixed * Moved Glyphs to ThemeScope * Removed test code
* Eliminate LineCanvas.Has params array allocation Inline ReadOnlySpan arguments do not incur heap allocation compared to regular arrays. * Allocate once LineCanvas.Exactly corner intersection arrays --------- Co-authored-by: Tig <[email protected]>
