Doing vertex data interleaved like this requires all the attributes to have the same size. I am able to get away with this since I pack everything into SDL_GPU_VERTEXELEMENTFORMAT_UBYTE4. Interleaved vertex buffers with mixed data sizes seems like a good place for using an inverted table and a C function to write it onto a transfer buffer row-by-row. Inverted tables also have the added benefit of squeezing the space used by each column if the numbers fall into a certain range. For example, with mock data: v_attrib ← ('p.x'⋄'p.y'⋄'p.z'⋄'n.x'⋄'n.y'⋄'n.z'⋄'r'⋄'g'⋄'b') ⋄ vb1←?(0 0 0 0 0 0 256 256 256)⍴⍨10000,≢v_attrib ⋄ vb2←{↑¨⊂⍤¯1⍉⍵}vb1, calling th system function ⎕SIZE 'vb1' 'vb2' returns 720040 and 540392 bytes respectively. ↩︎，推荐阅读新收录的资料获取更多信息
}try-catch does not change your function’s return type. It’s a local error-handling boundary — it consumes the error instead of propagating it. If you need the function to still return Result, use ? outside the try block or return explicitly from within catch:，这一点在新收录的资料中也有详细论述
