Struct PloidyMap 

pub struct PloidyMap { /* private fields */ }

Maps genomic positions to ploidy values, supporting a global default with per-contig and per-region overrides.

Overrides are processed in order and use last-writer-wins semantics: later entries override earlier ones for overlapping positions. This allows patterns like:

--ploidy 2 --ploidy-override chrX=1 --ploidy-override chrX:10001-2781479=2

which sets diploid genome-wide, then haploid chrX, then diploid PAR1 on chrX.

Implementations

impl PloidyMap

pub fn new(default_ploidy: u8, override_specs: &[String]) -> Result<Self>

Create a new ploidy map with the given default and overrides.

Override strings have the format CONTIG=PLOIDY (whole contig) or CONTIG:START-END=PLOIDY (1-based inclusive coordinates, converted internally to 0-based half-open).

Errors

Returns an error if any override string is malformed.

pub fn ploidy_at(&self, contig: &str, position: u32) -> u8

Look up the ploidy for a specific contig and 0-based position.

Returns the last matching override, or the default if no override applies.

pub fn default_ploidy(&self) -> u8

Return the default ploidy.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for PloidyMap

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