triepack
Compressed trie dictionary format (.trp) — compact binary key-value storage
with fast lookups and prefix search.
This is the native Python implementation: pure Python, no dependencies, no C extension to build. It reads and writes the same bytes as the C reference library and the JavaScript, Go, Rust, Swift, Java and Kotlin implementations.
Install
pip install triepack
Use
from triepack import encode, decode
buf = encode({"hello": 42, "world": "foo"})
# buf is bytes holding the .trp binary
result = decode(buf)
print(result) # {'hello': 42, 'world': 'foo'}
Values
| Python | .trp type |
|---|---|
None |
null |
bool |
bool |
int >= 0 |
uint |
int < 0 |
int |
float |
float64 |
str |
string (UTF-8) |
bytes |
blob |
Decoding also accepts float32 values written by other implementations, widening them to a Python float. Python integers are arbitrary precision, so the full 64-bit signed and unsigned ranges round-trip exactly.
Format
Every buffer carries a 32-byte header, a bit-packed prefix trie, a typed value store and a CRC-32. Keys are stored once per shared prefix, and symbols are packed at the minimum width the key alphabet needs.
The encoder is deterministic: the same input produces the same bytes in every implementation, which is checked by a shared conformance suite that all nine implementations run.
