Struct Minimizer64 

pub struct Minimizer64<const K: u8, const W: u8>(pub u64);

Minimizer-selected packed canonical kmer key stored in 64 bits.

Minimizer64<K, W> stores one canonical K-mer chosen from a longer sequence using minimizer selection over a window of W consecutive K-mers. The effective sequence span examined by the selector is therefore K + W - 1 bases.

When multiple minimizer candidates are produced for a sequence, dryice reduces them to a single record key by taking the minimum canonical packed value. This keeps the result deterministic and stable under reverse-complement transforms.

Implementations

impl<const K: u8, const W: u8> Minimizer64<K, W>

pub fn try_from_sequence(seq: &[u8]) -> Result<Option<Self>, DryIceError>

Derive a minimizer-selected canonical kmer key from a sequence.

Errors

Returns an error only for unexpected internal failures. Expected no-key outcomes such as short or ambiguous sequences return Ok(None).

This constructor currently uses simd-minimizers internally for canonical minimizer discovery, but dryice owns the public reduction semantics: one key per record, chosen as the minimum selected canonical packed value.
