Struct las::reader::Reader

pub struct Reader<'a> { /* private fields */ }

Reads LAS data.

Implementations

impl<'a> Reader<'a>

pub fn new<R: Read + Seek + Send + Debug + 'a>(read: R) -> Result<Reader<'a>>

Creates a new reader.

This does not wrap the Read in a BufRead, so if you’re concered about performance you should do that wrapping yourself (or use from_path).

Examples

use std::io::BufReader;
use std::fs::File;
let file = File::open("tests/data/autzen.las").unwrap();
let reader = Reader::new(BufReader::new(file)).unwrap();

impl<'a> Reader<'a>

pub fn from_path<P: AsRef<Path>>(path: P) -> Result<Reader<'a>>

Creates a new reader from a path.

The underlying File is wrapped in a BufReader for performance reasons.

Examples

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