Struct las::stream::Stream
[−]
[src]
pub struct Stream<R: Read> {
// some fields omitted
}A stream of las points.
Methods
impl Stream<BufReader<File>>
fn from_path<P: AsRef<Path>>(path: P) -> Result<Stream<BufReader<File>>>
Opens a new stream for the given path.
Examples
use las::stream::Stream; let stream = Stream::from_path("data/1.0_0.las").unwrap();
impl<R: Read + Seek> Stream<R>
fn new(reader: R) -> Result<Stream<R>>
Creates a new stream for a given Read object, consuming the read.
Examples
use std::fs::File; use las::stream::Stream; let file = File::open("data/1.0_0.las").unwrap(); let stream = Stream::new(file);
fn next_point(&mut self) -> Result<Option<Point>>
Returns the next point in this stream.
Examples
use las::stream::Stream; let mut stream = Stream::from_path("data/1.0_0.las").unwrap(); let point = stream.next_point().unwrap(); assert!(point.is_some()); let point = stream.next_point().unwrap(); assert!(point.is_none());
impl<R: Read> Stream<R>
fn header(&self) -> Header
Returns this stream's las header.
Examples
use las::stream::Stream; let stream = Stream::from_path("data/1.0_0.las").unwrap(); let header = stream.header();
fn vlrs(&self) -> &Vec<Vlr>
Returns a reference to this stream's vlrs.
Examples
use las::stream::Stream; let stream = Stream::from_path("data/1.0_0.las").unwrap(); let vlrs = stream.vlrs();
fn npoints(&self) -> u32
Returns the number of points in this lasfile, as specified by the header.
Examples
use las::stream::Stream; let stream = Stream::from_path("data/1.0_0.las").unwrap(); assert_eq!(1, stream.npoints());
fn eof(&self) -> bool
Returns true if this stream is at the end of the file.
Examples
use las::stream::Stream; let mut stream = Stream::from_path("data/1.0_0.las").unwrap(); assert!(!stream.eof()); let _ = stream.next_point().unwrap(); assert!(stream.eof());
