Struct noodles_cram::crai::AsyncWriter

pub struct AsyncWriter<W> { /* fields omitted */ }

An async CRAM index writer.

Implementations

impl<W> Writer<W> where
    W: AsyncWrite + Unpin, 

pub fn new(inner: W) -> Self

Creates an async CRAM index writer.

Examples

use noodles_cram::crai;
let writer = crai::AsyncWriter::new(Vec::new());

pub fn into_inner(self) -> W

Returns the underlying writer.

Examples

use noodles_cram::crai;
let writer = crai::AsyncWriter::new(Vec::new());
assert!(writer.into_inner().is_empty());

pub async fn shutdown(&mut self) -> Result<()>

Shuts down the output stream.

Examples

use noodles_cram::crai;
let mut writer = crai::AsyncWriter::new(Vec::new());
writer.shutdown().await?;

pub async fn write_index(&mut self, index: &[Record]) -> Result<()>

Writes a CRAM index.

Examples

use noodles_bam as bam;
use noodles_cram::crai;

let mut writer = crai::AsyncWriter::new(Vec::new());

let index = vec![crai::Record::new(
    bam::record::ReferenceSequenceId::try_from(0).map(Some)?,
    10946,
    6765,
    17711,
    233,
    317811,
)];

writer.write_index(&index).await?;
