Module las::writer

Write las points.

A Writer uses a Header for its configuration:

use std::io::Cursor;
use las::{Writer, Header};
let mut header = Header::from((1, 4));
let writer = Writer::new(Cursor::new(Vec::new()), header).unwrap();

The set of optional fields on the point format and the points must match exactly:

use std::io::Cursor;
use las::{Builder, Write, Writer, Point};
use las::point::Format;
use las::Color;

let mut builder = Builder::default();
builder.point_format = Format::new(1).unwrap();
let mut writer = Writer::new(Cursor::new(Vec::new()), builder.into_header().unwrap()).unwrap();

let mut point = Point::default(); // default points don't have any optional attributes
assert!(writer.write(point.clone()).is_err());

point.gps_time = Some(42.); // point format 1 requires gps time
writer.write(point.clone()).unwrap();

point.color = Some(Color::new(1, 2, 3));
assert!(writer.write(point).is_err()); // the point's color would be lost
