Struct Vlr 

pub struct Vlr {
    pub user_id: String,
    pub record_id: u16,
    pub description: String,
    pub data: Vec<u8>,
}

A variable length record.

Fields

user_id: String

The user that created this record.

This value is often an official, “registered” user_id, such as “LASF_Spec” or “LASF_Projection”.

record_id: u16

This value specifies the type of record, and depends on the user id.

description: String

Textual description of these data.

data: Vec<u8>

The data themselves.

Implementations

impl Vlr

pub fn is_copc_info(&self) -> bool

Returns true if this Vlr is the Copc info Vlr.

Examples

use las::Vlr;

let mut vlr = Vlr::default();
assert!(!vlr.is_copc_info());
vlr.user_id = "copc".to_string();
vlr.record_id = 1;
assert!(&vlr.is_copc_info());

impl Vlr

pub fn is_copc_hierarchy(&self) -> bool

Returns true if this Vlr is the Copc Hierarchy Vlr.

Examples

use las::Vlr;

let mut vlr = Vlr::default();
assert!(!vlr.is_copc_hierarchy());
vlr.user_id = "copc".to_string();
vlr.record_id = 1000;
assert!(vlr.is_copc_hierarchy());

impl Vlr

pub fn new(raw_vlr: Vlr) -> Vlr

Creates a vlr from a raw vlr.

Examples

use las::{Vlr, raw};
let raw_vlr = raw::Vlr::default();
let vlr = Vlr::new(raw_vlr);

pub fn into_raw(self, is_extended: bool) -> Result<Vlr>

Converts this vlr to a raw vlr.

Examples

use las::Vlr;
let raw_vlr =  Vlr::default().into_raw(false).unwrap();
let raw_evlr =  Vlr::default().into_raw(true).unwrap();

pub fn len(&self, is_extended: bool) -> usize

Returns the total length of this vlr, header and data.

Examples

use las::Vlr;

let mut vlr = Vlr::default();
assert_eq!(54, vlr.len(false));
assert_eq!(60, vlr.len(true));
vlr.data = vec![0];
assert_eq!(55, vlr.len(false));

pub fn is_empty(&self) -> bool

Returns true if the data of this vlr is empty.

Examples

use las::Vlr;
let mut vlr = Vlr::default();
assert!(vlr.is_empty());
vlr.data = vec![42];
assert!(!vlr.is_empty());

pub fn has_large_data(&self) -> bool

Returns true if this vlr must be extended due to large data size.

Examples

use las::Vlr;
use std::u16;
let mut vlr = Vlr::default();
assert!(!vlr.has_large_data());
vlr.data = vec![0; u16::MAX as usize + 1 ];
assert!(vlr.has_large_data());

pub fn is_crs(&self) -> bool

Check if the vlr is a projection (coordinate reference system) VLR

Examples

use las::Vlr;
let mut vlr = Vlr::default();
vlr.user_id = "LASF_Projection".to_string();
vlr.record_id = 2112;
assert!(vlr.is_crs());

pub fn is_wkt_crs(&self) -> bool

Returns true if it’s a well-known WKT coordinate reference system VLR.

Examples

use las::Vlr;
let mut vlr = Vlr::default();
vlr.user_id = "LASF_Projection".to_string();
vlr.record_id = 2112;
assert!(vlr.is_wkt_crs());

pub fn is_geotiff_crs(&self) -> bool

Returns true if it’s a geotiff coordinate reference system VLR.

Examples

use las::Vlr;
let mut vlr = Vlr::default();
vlr.user_id = "LASF_Projection".to_string();
vlr.record_id = 34735;
assert!(vlr.is_geotiff_crs());

Trait Implementations

impl Clone for Vlr

fn clone(&self) -> Vlr

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Vlr

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Vlr

fn default() -> Vlr

Returns the “default value” for a type.

impl PartialEq for Vlr

fn eq(&self, other: &Vlr) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&Vlr> for CopcInfoVlr

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &Vlr) -> Result<Self>

Performs the conversion.

impl TryFrom<&Vlr> for LazVlr

type Error = Error

The type returned in the event of a conversion error.

fn try_from(vlr: &Vlr) -> Result<LazVlr>

Performs the conversion.
