tson-bin — Terse JSON binary format for Python
TSON is a compact, schema-deduplicated binary format for JSON — field names are stored once, repeated strings are interned, giving 60–70% size reduction on repetitive data (API payloads, telemetry, config). These are the Python bindings (a native extension built in Rust via PyO3).
The PyPI distribution is
tson-binbut it imports astson.
Install
pip install tson-bin
import tson
Usage
import tson
# Compile a JSON string to TSON binary, and back
blob = tson.dumps('{"name": "Alice", "age": 30}') # -> bytes
obj = tson.loads(blob) # -> {"name": "Alice", "age": 30}
# Encode a Python object directly (no JSON string in between)
blob = tson.emit({"temp": 22.5, "status": "nominal"})
# File I/O
tson.dump('{"msg": "hello"}', "message.tson")
obj = tson.load("message.tson")
