Struct noodles_bcf::Writer [−][src]
pub struct Writer<W> where
W: Write, { /* fields omitted */ }
Expand description
A BCF writer.
Implementations
Creates a BCF writer with a default compression level.
The given stream is wrapped in a BGZF encoder.
Examples
use noodles_bcf as bcf;
let writer = bcf::Writer::new(Vec::new());
Returns a reference to the underlying writer.
Examples
use noodles_bcf as bcf;
let writer = bcf::Writer::new(Vec::new());
assert!(writer.get_ref().is_empty());
Attempts to finish the output stream.
This is typically only manually called if the underlying stream is needed before the writer is dropped.
Examples
use noodles_bcf as bcf;
let mut writer = bcf::Writer::new(Vec::new());
writer.try_finish()?;
Writes a BCF file format.
Examples
use noodles_bcf as bcf;
let mut writer = bcf::Writer::new(Vec::new());
writer.write_file_format()?;
Writes a VCF header.
Examples
use noodles_bcf as bcf;
use noodles_vcf as vcf;
let mut writer = bcf::Writer::new(Vec::new());
let header = vcf::Header::default();
writer.write_header(&header)?;
Writes a VCF record.
Examples
use noodles_bcf::{self as bcf, header::StringMap};
use noodles_vcf::{self as vcf, header::Contig, record::Position};
let mut writer = bcf::Writer::new(Vec::new());
let header = vcf::Header::builder()
.add_contig(Contig::new("sq0"))
.build();
writer.write_header(&header)?;
let string_map = StringMap::from(&header);
let record = vcf::Record::builder()
.set_chromosome("sq0".parse()?)
.set_position(Position::try_from(8)?)
.set_reference_bases("A".parse()?)
.build()?;
writer.write_vcf_record(&header, &string_map, &record)?;
