Struct rust_htslib::bcf::Writer

pub struct Writer { /* fields omitted */ }

A VCF/BCF writer.

Methods

impl Writer

pub fn from_path<P: AsRef<Path>>(
    path: P,
    header: &Header,
    uncompressed: bool,
    vcf: bool
) -> Result<Self, BCFPathError>

Create a new writer that writes to the given path.

Arguments

• path - the path.
• header - header definition to use
• uncompressed - disable compression
• vcf - write VCF instead of BCF

pub fn from_url(
    url: &Url,
    header: &Header,
    uncompressed: bool,
    vcf: bool
) -> Result<Self, BCFError>

pub fn from_stdout(
    header: &Header,
    uncompressed: bool,
    vcf: bool
) -> Result<Self, BCFError>

pub fn header(&self) -> &HeaderView

pub fn empty_record(&self) -> Record

Create empty record for writing to this writer. The record can be reused multiple times.

pub fn translate(&mut self, record: &mut Record)

Translate record to header of this writer.

pub fn subset(&mut self, record: &mut Record)

Subset samples of record to match header of this writer.

pub fn write(&mut self, record: &Record) -> Result<(), WriteError>

pub fn set_threads(&mut self, n_threads: usize) -> Result<(), ThreadingError>

Activate multi-threaded BCF write support in htslib. This should permit faster writing of large BCF files.

Arguments

• n_threads - number of extra background writer threads to use, must be > 0.
