Crate rust_aec 

rust-aec is a pure Rust decoder for CCSDS 121.0-B-3 Adaptive Entropy Coding (AEC).

Primary goal: support GRIB2 Data Representation Template 5.0 = 42 (CCSDS/AEC) without requiring native libaec.

Quick start

use rust_aec::{decode, flags_from_grib2_ccsds_flags, AecParams};

// In a real GRIB2 pipeline, `payload` is Section 7 and `num_points` comes from Section 5.
// This snippet focuses on API shape and compiles without external files.
let payload: Vec<u8> = Vec::new();
let num_points: usize = 0;

let params = AecParams::new(12, 32, 128, flags_from_grib2_ccsds_flags(0x0e));
let decoded = decode(&payload, params, num_points);
assert!(decoded.is_ok());
