Struct noodles_gff::io::Writer

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

A GFF writer.

Implementations

impl<W> Writer<W>

where W: Write,

pub fn new(inner: W) -> Self

Creates a GFF writer.

Examples

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

pub fn write_line(&mut self, line: &Line) -> Result<()>

Writes a Line.

Examples

use noodles_gff as gff;
use gff::line::Line;

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

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

let comment = Line::Comment(String::from("noodles"));
writer.write_line(&comment)?;

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

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

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

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

Writes a GFF directive.

Examples

use noodles_gff as gff;

let mut writer = gff::io::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<()>

Writes a GFF record.

Examples

use noodles_gff as gff;

let mut writer = gff::io::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[..]);
