Methods
impl Vlr
fn read_from<R: Read>(reader: &mut R) -> Result<Vlr>
Reads a Vlr from a Read.
Examples
use std::fs::File; use std::io::{Seek, SeekFrom}; use las::header::Header; use las::vlr::Vlr; let ref mut reader = File::open("data/1.0_0.las").unwrap(); let header = Header::read_from(reader).unwrap(); reader.seek(SeekFrom::Start(header.header_size as u64)).unwrap(); let vlr = Vlr::read_from(reader);
fn new() -> Vlr
fn len(&self) -> u32
Returns the length of this variable length record in bytes.
Examples
use las::vlr::Vlr; let vlr = Vlr::new(); assert_eq!(54, vlr.len());
fn write_to<W: Write>(&self, writer: &mut W) -> Result<u32>
Writes this vlr to a Write.
Examples
use std::io::Cursor; use las::vlr::Vlr; let vlr = Vlr::new(); let ref mut writer = Cursor::new(Vec::new()); vlr.write_to(writer).unwrap();
