Browserslist-rs Gets Major Refactor, Cutting Binary Size by Over 1MB
Browserslist-rs now uses static data to reduce binary size by over 1MB, improving memory use and performance for Rust-based frontend tools.
This library provides efficient run-length encoded (RLE) operations for binary masks in Python. It is designed to be fast and memory efficient, and is particularly useful for working with large datasets. The library provides an intuitive and extensive object-oriented interface as well as a simpler functional one. To achieve high efficiency, the core functionality is implemented in C, and wrapped via Cython.
RLEMaskLib is fully compatible with the COCO mask format (in the form of dictionaries) but can also work directly with runlength sequences.
The library provides many operations on masks, including:
This library originates as a fork of the COCO API's pycocotools.mask
module (which was originally written by Piotr Dollár and Tsung-Yi Lin) but now mostly consists of new code.
pip install rlemasklib
