#mmap

cross-platform Rust API for memory mapped IO

Compact, immutable string↔id indexes for huge catalogs: FST prefix/range/fuzzy + minimal-perfect-hash, from 1.3 B/key, zero-copy mmap load. Rust core, Python bindings.

Crates for memory management.

SnapDB — Extremely lightweight lightning-fast in-memory database for Python. Zero-copy reads, single-file, pure Python.

Small, focused Go packages that bind native OS and hardware APIs without CGo

Off-heap Go memory allocator with lock-free slab allocation, generation-safe Reset, and huge page support. Zero heap pressure.

Ultra-fast, zero-allocation, authenticated in-memory & persistent key-value cache in pure Go. mmap arena allocator with no GC, S3-FIFO eviction, AES-256-GCM encryption at rest, LZ4 compression, TCP/QUIC transports, append-only WAL with cold-start replay.

Fast security-aware file tree walker - gitignore, binary detection, memmap2, parallel
