Struct FecOpts 

pub struct FecOpts<'a> {
    pub bp_max_iter: u32,
    pub osd_depth: u32,
    pub ap_mask: Option<(&'a [u8], &'a [u8])>,
}

Options controlling FEC decoding depth / fall-backs.

This is deliberately a plain data struct rather than a trait — it describes how to decode, not what code to use. Codecs ignore fields that don’t apply (e.g. convolutional decoders ignore osd_depth).

Fields

bp_max_iter: u32

Maximum belief-propagation iterations (LDPC).

osd_depth: u32

Ordered-statistics-decoding search depth (0 disables OSD fallback).

ap_mask: Option<(&'a [u8], &'a [u8])>

Optional a-priori hint: bits whose LLR should be clamped to a strong known value before decoding. Some((mask, values)) where mask[i] == 1 means values[i] is locked to values[i].

Lifetime is per-call: the caller allocates the AP vectors for the duration of this decode — typical usage builds a Vec<u8> from an ApHint and borrows into FecOpts for a single decode_soft call.
