Struct noodles::cram::crai::Writer [−][src]
pub struct Writer<W> where
W: Write, { /* fields omitted */ }
Expand description
A CRAM index writer.
Implementations
Creates a CRAM index writer.
Examples
use noodles_cram::crai;
let writer = crai::Writer::new(Vec::new());
Returns a reference to the underlying writer.
Examples
use noodles_cram::crai;
let writer = crai::Writer::new(Vec::new());
assert!(writer.get_ref().is_empty());
Attempts to finish the output stream and returns the underlying writer.
This is typically only manually called if the underlying stream is needed before the writer is dropped.
Examples
use noodles_cram::crai;
let writer = crai::Writer::new(Vec::new());
let empty_gz = [31, 139, 8, 0, 0, 0, 0, 0, 0, 255, 3, 0, 0, 0, 0, 0, 0, 0, 0, 0];
assert_eq!(writer.finish()?, empty_gz);
Writes a CRAM index.
Examples
use noodles_bam as bam;
use noodles_cram::crai;
let mut writer = crai::Writer::new(Vec::new());
let index = vec![crai::Record::new(
bam::record::ReferenceSequenceId::try_from(0).map(Some)?,
10946,
6765,
17711,
233,
317811,
)];
