Crate fec 

Forward error correction for SDR, space, and satellite links.

The two codecs each live in their own module. convolutional holds the Viterbi encoder and decoder. reed_solomon holds the Reed-Solomon codec, including the standard CCSDS (255,223) code.

Each module names its types plainly as Encoder and Decoder. The crate root also re-exports them under Conv- and Rs-prefixed aliases, so both codecs can be used in one scope without a name clash. Reach for convolutional::Encoder when you work with one codec, or ConvEncoder and RsEncoder when you want both.

The Reed-Solomon codec and the scalar convolutional codec build on stable Rust. The SIMD convolutional decoder is behind the simd feature, which needs a nightly compiler because it uses portable_simd.
