Struct ros_pointcloud2::PointMeta

pub struct PointMeta { /* private fields */ }

Meta data representation for a point

This struct is used to store meta data in a fixed size byte buffer along the with the datatype that is encoded so that it can be decoded later.

Example

use ros_pointcloud2::PointMeta;

let original_data: f64 = 1.0;
let meta = PointMeta::new(original_data);
let my_data: f64 = meta.get().unwrap();

Implementations

impl PointMeta

pub fn new<T: FromBytes>(value: T) -> Self

Create a new PointMeta from a value

Example

let meta = ros_pointcloud2::PointMeta::new(1.0);

pub fn get<T: FromBytes>(&self) -> Result<T, ConversionError>

Get the value from the PointMeta. It will return None if the datatype does not match.

Example

let original_data: f64 = 1.0;
let meta = ros_pointcloud2::PointMeta::new(original_data);
let my_data: f64 = meta.get().unwrap();
