tink-crystal
tink data-flow node frame protocol — Crystal module (no dependencies). Universal and language-agnostic: any component that obeys the frame protocol can join a tink pipeline.
帧 = [ len: u32 BE ][ payload: len 字节 ][ crc: u32 BE ]
len = payload 字节数
crc = CRC32-IEEE(payload)（多项式 0xEDB88320）
Mirrors std/tink.tie (tie standard library) and the other-language tink libraries; pure functions over Bytes, IO (stdin/stdout) left to the caller. Names follow the Crystal convention (Tink module, snake_case methods).
API (module Tink)
| function | description |
|---|---|
Tink.crc32(data) -> UInt32 |
CRC32-IEEE over a Bytes. Check vector: Tink.crc32("123456789") == 0xCBF43926 |
Tink.frame_encode(payload) -> Bytes |
encode a payload into a full frame [len][payload][crc] |
Tink.frame_next(bytes, pos) -> Frame? |
parse one frame at pos, verify CRC; Frame(payload, next) on success, nil on out-of-bounds / mismatch |
Tink.frame_skip(bytes, pos) -> Int32? |
skip one frame at pos without copying or verifying; nil on out-of-bounds |
Usage
require "./tink"
frame = Tink.frame_encode(Bytes[1, 2, 3])
got = Tink.frame_next(frame, 0) # Tink::Frame?
Test
crystal run test_tink.cr
