fast_rust 0.1.0

Rust-powered image and data kernels for Flutter and Dart over zero-copy dart:ffi: photo recoloring, flood fill, blur, SHA-256 and sorting.

0.1.0

• Initial release. Rust kernels called through zero-copy dart:ffi @Native functions; a native-assets build hook runs cargo for the target platform (Android, iOS, macOS, Linux, Windows).
• Photo recoloring: FastRust.recolorRegionRgba selects a connected region of a real image by color tolerance (magic wand) and tints it while keeping each pixel's brightness, so texture survives.
• Pixel-art coloring: floodFillRgba (scanline bucket fill with tolerance) and coloringPageRgba (generated coloring pages).
• Image processing: multi-threaded boxBlurRgba (O(pixels) for any radius) and grayscaleRgba.
• sha256, sortFloat64 (IEEE-754 total order), countPrimes, dot, and a multi-threaded mandelbrotRgba.
• ...Async variants run on a background isolate with non-leaf calls.
• DartReference: pure-Dart versions of every kernel, used by the tests to check that Rust output matches bit for bit.
