Module las::reader

Read las points.

If you’re reading any significant number of points, you’ll want to make sure you’re using a BufRead instead of just a Read:

use std::fs::File;
use std::io::BufReader;
use las::Reader;

let read = BufReader::new(File::open("tests/data/autzen.las").unwrap());
let reader = Reader::new(read).unwrap();

Reader::from_path does this for you:

use las::Reader;
let reader = Reader::from_path("tests/data/autzen.las").unwrap();

Ccompressed files are supported when using the feature “laz”:

use las::Reader;
if cfg!(feature = "laz") {
 assert!(Reader::from_path("tests/data/autzen.laz").is_ok());
} else {
 assert!(Reader::from_path("tests/data/autzen.laz").is_err());
}

Use Reader::read to read one point, and Reader::points to get an iterator over Result<Point>:

use las::{Read, Reader};
let mut reader = Reader::from_path("tests/data/autzen.las").unwrap();
let first_point = reader.read().unwrap().unwrap();
let the_rest = reader.points().map(|r| r.unwrap()).collect::<Vec<_>>();
