Enum DecoyMethod 

pub enum DecoyMethod {
    Shuffle,
    Reverse,
    RandomUniform,
    RandomFreq,
    Markov {
        order: usize,
    },
    DeBruijn {
        k: usize,
    },
    DeBruijnCleave {
        k: usize,
    },
}

Decoy generation method, parsed from the decoy_method config string.

Variants

Shuffle

Peptide-interior shuffle (handled in database.rs, not here).

Reverse

RandomUniform

RandomFreq

Markov

Fields

order: usize

DeBruijn

Fields

k: usize

DeBruijnCleave

Cleavage-site-preserving de Bruijn: K/R/P stay at their exact positions (so the tryptic peptide lengths/count match the target exactly), and the remaining positions are filled by a back-off Markov walk (orders k..1..0) over real sequence — every residue drawn from real high-order context, no abrupt restarts. The most realistic decoy that still isn’t a plain reversal.

Fields

k: usize
