Eignex

Produces short deterministic string tokens for strict-length contexts using a compact PackedFormat (bitset headers, varints/zigzag), optional transforms (checksum, encryption, ECC), and Base62/36/64/85 codecs.

#serializer, #serialization, #kotlin-serialization, #fileformat

Fast, deterministic integer permutations producing keyed, reversible bijections over ranges. Memory-efficient, invertible shuffles with cycle-walking, xor-shift-multiply mixing, seeded determinism, and full/unsigned domain support.

#utility, #language-extensions

Compute streaming, mergeable statistics using constant memory: summaries, quantile and cardinality sketches, decaying/regression estimators, composable adapters, wire-portable schemas, and bandits.

#windows, #web, #wasm, #macos, #linux, #concurrency

Declare singleton schemas offering typed compile-time field access and serializable wire definitions; consumers decode, diff, compose, namespaced-merge, and walk entries without shared code.

#serialization

Serializable dense and sparse matrix and vector containers, BLAS-like arithmetic and factorizations, sparse Markowitz LU and EtaBasis updates, with runtime-swappable high-performance compute backend.
