Struct las::Reader

pub struct Reader<R> {
    pub header: Header,
    // some fields omitted
}

Takes bytes and turns them into points and associated metadata.

Fields

header: Header

LAS header.

Methods

impl Reader<BufReader<File>>

fn from_path<P: AsRef<Path>>(path: P) -> Result<Reader<BufReader<File>>>

Creates a reader for a file at the given path.

Examples

let reader = Reader::from_path("data/1.0_0.las").unwrap();

impl<R: Read + Seek> Reader<R>

fn new(read: R) -> Result<Reader<R>>

Creates a new reader from a Read object.

While Reader::from_path wraps the underlying File in a BufReader, this method does no such work for you. If you're planning on doing lots of reads, you should probably wrap your Read in a BufReader for performance reasons.

Examples

use std::io::{Cursor, Read};
use std::fs::File;
let mut buf = Vec::new();
File::open("data/1.0_0.las").unwrap().read_to_end(&mut buf).unwrap();
let reader = Reader::new(Cursor::new(buf));

fn read(&mut self) -> Result<Option<Point>>

Reads a point.

Examples

let mut reader = Reader::from_path("data/1.0_0.las").unwrap();
// This reader has one point.
let point = reader.read().unwrap().unwrap();
assert!(reader.read().unwrap().is_none());

fn read_to_end(&mut self) -> Result<Vec<Point>>

Creates a vector with all the points in this lasfile.

If any of the reads causes an error, returns that error.

Examples

let mut reader = Reader::from_path("data/1.0_0.las").unwrap();
let points = reader.read_to_end().unwrap();

fn iter_mut(&mut self) -> IterMut<R>

Returns an iterator over points.

Examples

let mut reader = Reader::from_path("data/1.0_0.las").unwrap();
let points = reader.iter_mut().collect::<Result<Vec<_>, _>>().unwrap();
