Struct Reader

pub struct Reader<R> { /* private fields */ }

An async FASTA index reader.

Implementations

impl<R> Reader<R>

where R: AsyncBufRead + Unpin,

pub fn new(inner: R) -> Self

Creates an async FASTA index reader.

Examples

use noodles_fasta::fai;
let data = [];
let mut reader = fai::r#async::io::Reader::new(&data[..]);

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

Reads a FASTA index.

The position of the stream is expected to be at the start or at the start of a record.

Examples

use noodles_fasta::fai;

let data = b"sq0\t13\t5\t80\t81\nsq1\t21\t19\t80\t81\n";
let mut reader = fai::r#async::io::Reader::new(&data[..]);

let index = reader.read_index().await?;

assert_eq!(index, fai::Index::from(vec![
    fai::Record::new(String::from("sq0"), 13, 5, 80, 81),
    fai::Record::new(String::from("sq1"), 21, 19, 80, 81),
]));
