Enum InnerReader 

pub enum InnerReader {
    Unindexed(Reader),
    Indexed(IndexedReader),
}

Internal enum wrapping indexed or unindexed htslib readers.

This allows the Reader to work with both indexed and unindexed VCF/BCF files through a unified interface.

Variants

Unindexed(Reader)

An unindexed reader (sequential access only).

Indexed(IndexedReader)

An indexed reader (supports region queries).

Implementations

impl InnerReader

pub fn header_ptr(&self) -> *mut bcf_hdr_t

Get the raw header pointer.

pub fn empty_record(&self) -> Record

Create an empty record for reading into.

pub fn read_record(&mut self, record: &mut Record) -> Option<Result<(), Error>>

Read the next record into the provided buffer.

Returns None at EOF, Some(Ok(())) on success, or Some(Err(...)) on error.

pub fn fetch( &mut self, chrom: &str, start0: u64, end0: Option<u64>, ) -> Result<(), Error>

Fetch records from a genomic region (indexed readers only).

After calling this, subsequent read_record calls will return only records overlapping the specified region.
