Struct BinnedQualityCodec 

pub struct BinnedQualityCodec;

Illumina-style 8-level quality score binning.

This is an explicitly lossy encoding that maps Phred quality scores into 8 bins, reducing entropy for better downstream compression while preserving the most important quality distinctions.

Bin boundaries and representative values:

Phred  0-1   → 0
Phred  2-9   → 6
Phred 10-19  → 15
Phred 20-24  → 22
Phred 25-29  → 27
Phred 30-34  → 33
Phred 35-39  → 37
Phred 40+    → 40

Quality bytes are assumed to be Phred+33 encoded (standard Sanger/Illumina 1.8+ encoding). The binned output is also Phred+33 encoded.

Trait Implementations

impl Clone for BinnedQualityCodec

fn clone(&self) -> BinnedQualityCodec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BinnedQualityCodec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BinnedQualityCodec

fn default() -> BinnedQualityCodec

Returns the “default value” for a type.

impl QualityCodec for BinnedQualityCodec

const TYPE_TAG: [u8; 16]

Stable type tag written into block headers.

const LOSSY: bool = true

Whether this encoding is lossy.

fn encode_into(quality: &[u8], output: &mut Vec<u8>) -> Result<(), DryIceError>

Encode raw quality score bytes, appending the encoded bytes directly into the provided output buffer.

fn decode_into( encoded: &[u8], _original_len: usize, output: &mut Vec<u8>, ) -> Result<(), DryIceError>

Decode an encoded buffer, appending the decoded quality bytes directly into the provided output buffer.

const IS_IDENTITY: bool = false

Whether the encoded form is identical to the raw input bytes.

fn encode(quality: &[u8]) -> Result<Vec<u8>, DryIceError>

Encode quality scores, returning a new allocated buffer.

fn decode(encoded: &[u8], original_len: usize) -> Result<Vec<u8>, DryIceError>

Decode an encoded buffer, returning a new allocated buffer.
