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

A GFF writer.

Implementations

impl<W> Writer<W> where
    W: Write, 

pub fn new(inner: W) -> Writer<W>

Creates a GFF writer.

Examples

use noodles_gff as gff;
let writer = gff::Writer::new(Vec::new());

pub fn get_ref(&self) -> &W

Returns a reference to the underlying writer.

Examples

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

pub fn write_directive(&mut self, directive: &Directive) -> Result<(), Error>

Writes a GFF directive.

Examples

use noodles_gff as gff;

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

let version = gff::Directive::GffVersion(Default::default());
writer.write_directive(&version)?;

assert_eq!(writer.get_ref(), b"##gff-version 3\n");

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

Writes a GFF record.

Examples

use noodles_gff as gff;

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

let version = gff::Directive::GffVersion(Default::default());
writer.write_directive(&version)?;

let record = gff::Record::default();
writer.write_record(&record)?;

let expected = b"##gff-version 3
.\t.\t.\t1\t1\t.\t.\t.\t.
";

assert_eq!(&writer.get_ref()[..], &expected[..]);
