Trait FecCodec 

pub trait FecCodec: Default + 'static {
    const N: usize;
    const K: usize;

    // Required methods
    fn encode(&self, info: &[u8], codeword: &mut [u8]);
    fn decode_soft(&self, llr: &[f32], opts: &FecOpts<'_>) -> Option<FecResult>;
}

Forward-error-correction codec: maps K information bits ↔ N codeword bits.

Implementors MUST be Default-constructible so generic pipeline code can obtain an instance via P::Fec::default() without plumbing state. Stateless codecs (matrices in const / static) are the common case.

Required Associated Constants

const N: usize

Codeword length.

const K: usize

Information-bit length.

Required Methods

fn encode(&self, info: &[u8], codeword: &mut [u8])

Systematic encode: info.len() == K, codeword.len() == N. The first K bits of codeword must equal info (systematic form).

fn decode_soft(&self, llr: &[f32], opts: &FecOpts<'_>) -> Option<FecResult>

Soft-decision decode from log-likelihood ratios.

llr.len() == N. On success returns the K information bits plus decoder statistics. On failure returns None.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
