Struct CountRowMap 

pub struct CountRowMap {
    pub row_to_gene: Vec<u32>,
    pub row_is_nascent: Vec<bool>,
    pub gene_names: Vec<Box<str>>,
    pub unparsed: Vec<usize>,
}

A count matrix’s feature axis interned onto a dense gene axis.

Row order is the matrix’s own and is never permuted; gene ids are assigned in first-seen row order, so gene_names is stable for a given input.

Fields

row_to_gene: Vec<u32>

row_to_gene[r] = gene id of row r, or NO_GENE.

row_is_nascent: Vec<bool>

row_is_nascent[r] = true when row r is the unspliced track. Always false for an unparsed row under either policy — such a row is not a nascent row, it is not a count row.

gene_names: Vec<Box<str>>

Gene keys in id order.

unparsed: Vec<usize>

Indices of rows that are not {gene}/count/{spliced|unspliced}, in row order. Empty on a well-formed gene-count matrix.

Implementations

impl CountRowMap

pub fn n_genes(&self) -> usize

pub fn n_rows(&self) -> usize

pub fn n_nascent_rows(&self) -> usize

Rows on the nascent track. Zero on a spliced-only matrix — a legitimate input that simply identifies no nascent-minus-mature contrast.
