I have a struct: struct DocPos { block: Uuid, offset: usize, flags: u32 } And lots of functions around it, for example: fn doc_pos_to_utf16_index(pos: DocPos) -> Utf16Index fn compare_positions(&self, a: &DocPos, b:…
Buffer initialization does not get optimized out
I have the following snippet (minimization of a similar problem encountered in real code): const N: usize = 32; fn read(block: &[u8; 8 * N]) -> [u64; N] { let (chunks, tail) = block.as_chunks();…

Building a candlestick chart engine on raw Canvas2D (no chart library)

How a web page can stream multi-GB local files to a Chromecast without uploading them
