Struct noodles_fasta::writer::Writer

pub struct Writer<W> { /* private fields */ }

A FASTA writer.

Implementations

impl<W> Writer<W>where
    W: Write,

pub fn builder(inner: W) -> Builder<W>

Creates a FASTA writer builder.

Examples

use noodles_fasta as fasta;
let writer = fasta::Writer::builder(Vec::new()).build();

pub fn new(inner: W) -> Self

Creates a FASTA writer.

Examples

use noodles_fasta as fasta;
let writer = fasta::Writer::new(Vec::new());

pub fn get_ref(&self) -> &W

Returns a reference to the underlying writer.

Examples

use noodles_fasta as fasta;
let writer = fasta::Writer::new(Vec::new());
assert!(writer.get_ref().is_empty());

pub fn write_record(&mut self, record: &Record) -> Result<()>

Writes a FASTA record.

Sequence lines are hard wrapped at 80 bases.

Examples

use noodles_fasta::{self as fasta, record::{Definition, Sequence}};

let mut writer = fasta::Writer::new(Vec::new());

let definition = Definition::new("sq0", None);
let sequence = Sequence::from(b"ACGT".to_vec());
let record = fasta::Record::new(definition, sequence);

writer.write_record(&record)?;

assert_eq!(writer.get_ref(), b">sq0\nACGT\n");
