Struct FeatureAnalyzer 

pub struct FeatureAnalyzer { /* private fields */ }

The shipped features egress, expressed as a ColumnAnalyzer — proof the trait carries the real production analyzer. Counts the rows it emits (folded into the receipt via ColumnAnalyzer::params).

Implementations

impl FeatureAnalyzer

pub fn rows(&self) -> u64

Number of feature rows written so far.

Trait Implementations

impl ColumnAnalyzer for FeatureAnalyzer

fn header(&self) -> Option<String>

Optional header written once, before any column (e.g. a TSV header line, including its trailing newline). Default: none.

fn params(&self) -> BTreeMap<String, String>

Parameters to fold into the run receipt (provenance). Default: none.

fn on_column( &mut self, col: &PileupColumn, contig: &str, out: &mut dyn Write, ) -> Result<()>

Process one callable pileup column, writing any output to out. Called in (contig, position) order; contig is the column’s contig name. Keep per-call state O(1) (or bounded) to preserve the memory contract.

impl Debug for FeatureAnalyzer

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

Formats the value using the given formatter.

impl Default for FeatureAnalyzer

fn default() -> FeatureAnalyzer

Returns the “default value” for a type.
