unstd

stdlib-faithful accelerated replacements. Each module wraps a native codec behind the call surface of the stdlib module it stands in for, so migrating a call site is an import swap, not a rewrite.

import json  # →
from unstd.serde import jsonx  # jsonx.dumps / jsonx.loads, same surface, faster

The base install is pure stdlib: depending on unstd adds zero third-party closure. Every accelerated backend rides an optional extra with a guarded import that falls back to the stdlib (or raises a clear ImportError where no fallback is faithful). Install unstd and you pay nothing. Install unstd[serde] and the serde modules light up.

Install

python3 -m pip install unstd
python3 -m pip install 'unstd[serde,ids,crypto]'

Groups

Group Extra Backend / fallback
serde unstd[serde] orjson / msgspec / pybase64 → stdlib json/base64
ids unstd[ids] blake3 / uuid-utils → hash requires the extra; uid falls back to stdlib UUIDv7
crypto unstd[crypto] blake3 (required; hashlib ships BLAKE2, a different algorithm)
time unstd[time] timeutil is pure stdlib; dateutil requires whenever, and timeutil's protobuf Timestamp bridge requires unstd[proto]
model unstd[model] pydantic (required)
rex unstd[rex] irregex → stdlib re
containers unstd[containers] sortedcontainers + immutables (required)
rand unstd[rand] numpy PCG64 → stdlib random; crypto is always secrets
pack unstd[pack] numpy → stdlib struct
clone unstd[clone] msgspec → copy.deepcopy
text unstd[text] rapidfuzz → stdlib difflib
audio unstd[audio] soundfile + numpy → stdlib wave
toml unstd[toml] read is tomllib; write requires tomlkit
proc — stdlib subprocess
fs — stdlib os
iters — stdlib itertools

proc, fs, and iters ship in the base install.

Prior art

  • orjson (Kloss) / msgspec (Fitzgerald) / pybase64 (aklomp libbase64) — the serde backends.
  • The guarded-optional-backend pattern is the one uvloop popularized: import the accelerator, fall back when it is absent.
