Struct noodles_fasta::fai::Reader

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

A FASTA index reader.

Implementations

impl<R> Reader<R>where R: BufRead,

pub fn new(inner: R) -> Self

Creates a FASTA index reader.

Examples

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

pub 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::Reader::new(&data[..]);
let index = reader.read_index()?;

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