  "message": "[rust bmp] Reduce fixed overhead for small decodes\n\nThis change adds a small memory-backed input path for Rusty BMP. When\nthe `SkStream` already exposes memory and the encoded BMP is small\n(\u003c\u003d4KB), the codec passes the bytes directly to Rust/image-rs\n`BmpDecoder` instead of wrapping the stream in `SkStreamAdapter` +\n`BufReader`. Larger or incremental streams continue to use the existing\nstreaming path.\n\nLocal Chromium decoder-boundary benchmarks show this reduces small-image\nRust overhead while preserving larger-image wins. For example, with the\nChromium-side memory-backed stream prep:\n\n - 24bit_1x1.bmp: Rust improves from ~6.2 us to ~4.3 us\n - pal4_1x1.bmp: Rust improves from ~7.4 us to ~5.3 us\n - bmp-size-32x32-8bpp.bmp remains ~73% faster than legacy C++\n - large 32bpp-topdown-320x240.bmp remains ~77% faster than legacy C++\n\nBug: 452666425\nChange-Id: I1d8975f31b7a66b158e8402341399a47dbfe26f4\nReviewed-on: https://skia-review.googlesource.com/c/skia/+/1283656\nCommit-Queue: Florin Malita \u003cfmalita@google.com\u003e\nReviewed-by: Łukasz Anforowicz \u003clukasza@google.com\u003e\nReviewed-by: Florin Malita \u003cfmalita@google.com\u003e\n",
