pub fn get_ref(&self) -> &Reader<R>

Returns a reference to the underlying reader.

pub fn get_mut(&mut self) -> &mut Reader<R>

Returns a mutable reference to the underlying reader.

pub fn into_inner(self) -> Reader<R>

Returns the underlying reader.

pub fn read_header(&mut self) -> Result<Header>

Reads the VCF header.

pub fn read_record( &mut self, header: &Header, record: &mut Record ) -> Result<usize>

Reads a single raw VCF record.

pub fn records<'r, 'h: 'r>( &'r mut self, header: &'h Header ) -> Records<'r, 'h, Reader<R>>

Returns an iterator over records starting from the current stream position.

pub fn read_lazy_record(&mut self, record: &mut Record) -> Result<usize>
