Struct ULogData 

pub struct ULogData { /* private fields */ }

Container for a single data row

Implementations

impl ULogData

pub fn new(data: Vec<u8>, formats: Vec<String>) -> Self

pub fn data(&self) -> &Vec<u8>

Get the unformatted data for this item

pub fn formats(&self) -> &Vec<String>

Get the data formatting for this item

pub fn items(&self) -> Vec<String>

Get the list of field names in this item

Examples

use std::fs::File;
use px4_ulog::parser::dataset::*;
let filename = format!(
    "{}/tests/fixtures/6ba1abc7-b433-4029-b8f5-3b2bb12d3b6c.ulg",
    env!("CARGO_MANIFEST_DIR")
);

let mut log_file = File::open(&filename).unwrap();
let items = log_file.get_dataset("vehicle_gps_position")
    .unwrap()
    .next()
    .unwrap()
    .items();
assert_eq!(items[0], "timestamp");
assert_eq!(items[1], "time_utc_usec");
assert_eq!(items.len(), 23);

pub fn iter(&self) -> ULogDataIter<'_>

Get an iterator for data fields

The iterator value will be a tuple of (&str, DataType) where the first item will be the field name and the second the value.

Examples

use std::fs::File;
use px4_ulog::parser::dataset::*;
let filename = format!(
    "{}/tests/fixtures/6ba1abc7-b433-4029-b8f5-3b2bb12d3b6c.ulg",
    env!("CARGO_MANIFEST_DIR")
);

let mut log_file = File::open(&filename).unwrap();
let mut dataset = log_file.get_dataset("vehicle_gps_position").unwrap();
let first_data = dataset.next().unwrap();
assert_eq!(first_data.iter().count(), 23);
