    marisa-trie

    1.1Kpytries/marisa-trie · Cython

    Static, memory-efficient trie-like data structures for Python, built on the marisa-trie C++ library. Strings stored inside can take up to 50x-100x less memory than in a standard Python dict, with comparable lookup speed and fast prefix search.

    goose

    607aardappel/goose · C++

    Goose is a memory-safe systems programming language with no heap allocator, garbage collector, or lifetime annotations. In its own benchmarks it runs faster than C++ and safe Rust while using less memory.

    rapl

    106JErnestoMtz/rapl · Rust

    rapl is a Rust library for N-dimensional arrays (ndarrays) that encodes the rank of an array in its type, so a rank mismatch becomes a compile error, combining ideas from NumPy and array languages like APL and BQN.
