Crate tensogram_szip 

Pure-Rust CCSDS 121.0-B-3 Adaptive Entropy Coding (AEC/SZIP).

This crate provides encode, decode, and range-decode functions with the same AecParams interface as the C libaec library. It can be used as a drop-in replacement for libaec-sys in environments where C FFI is unavailable (e.g. WebAssembly).

Example

use tensogram_szip::{aec_compress, aec_decompress, AecParams, AEC_DATA_PREPROCESS};

let data: Vec<u8> = (0..1024).map(|i| (i % 256) as u8).collect();
let params = AecParams {
    bits_per_sample: 8,
    block_size: 16,
    rsi: 128,
    flags: AEC_DATA_PREPROCESS,
};

let (compressed, offsets) = aec_compress(&data, &params).unwrap();
let decompressed = aec_decompress(&compressed, data.len(), &params).unwrap();
assert_eq!(decompressed, data);

Functions

aec_compress

Compress data using CCSDS 121.0-B-3 adaptive entropy coding.

aec_compress_no_offsets

Compress data without tracking RSI block offsets (slightly faster).

aec_decompress

Decompress an entire AEC-compressed stream.

aec_decompress_range

Decompress a partial byte range from AEC-compressed data using pre-computed RSI block bit offsets.
