Struct las::Writer

pub struct Writer<W: Seek + Write> { /* fields omitted */ }

Writes LAS data.

The LAS header needs to be re-written when the writer closes. For convenience, this is done via the Drop implementation of the writer. One consequence is that if the header re-write fails during the drop, a panic will result. If you want to check for errors instead of panicing, use close explicitly.

use std::io::Cursor;
{
    let mut writer = Writer::new(Cursor::new(Vec::new()), Default::default()).unwrap();
    writer.close().unwrap();
} // <- `close` is not called

Methods

impl<W: Seek + Write> Writer<W>

fn new(write: W, header: Header) -> Result<Writer<W>>

Creates a new writer.

Examples

use std::io::Cursor;
let writer = Writer::new(Cursor::new(Vec::new()), Default::default());

fn write(&mut self, point: &Point) -> Result<()>

Writes a point.

Examples

use std::io::Cursor;

let mut writer = Writer::new(Cursor::new(Vec::new()), Default::default()).unwrap();
writer.write(&Default::default()).unwrap();

fn close(&mut self) -> Result<()>

Close this writer.

A second call to close is a no-op.

Examples

use std::io::Cursor;
let mut writer = Writer::new(Cursor::new(Vec::new()), Default::default()).unwrap();
writer.close().unwrap();
writer.close().unwrap(); // <- no-op

impl Writer<BufWriter<File>>

fn from_path<P: AsRef<Path>>(
    path: P,
    header: Header
) -> Result<Writer<BufWriter<File>>>

Creates a new writer for a path.

Examples

let writer = Writer::from_path("/dev/null", Default::default());
