}

Data from the gps device.

Fields

mode: Fix

NMEA mode: 0=unknown, 1=no fix, 2=2D, 3=3D.

sats: u8

The number of satellites received by the GPS unit

sats_valid: u8

The number of satellites with valid information.

lon: f64

Longitude in degrees.

lat: f64

Latitude in degrees

alt_hae: f64

Altitude, height above ellipsoid, in meters.

alt_msl: f64

MSL Altitude in meters. The geoid used is rarely specified and is often inaccurate.

alt: f32

Deprecated. Altitude in meters. Use altHAE or altMSL.

track: f32

Course over ground, degrees from true north

speed: f32

Speed over ground, meters per second

climb: f32

Climb (positive) or sink (negative) rate, meters per second

time: String

Time/date stamp in ISO8601 format, UTC. May have a fractional part of up to .001sec precision.

epc: f32

Climb/sink error estimate in meters/sec, 95% confidence.

eps: f32

Speed error estimated in meters/sec, 95% confidence.

ept: f32

Estimated timestamp error (%f, seconds, 95% confidence).

epv: f32

Estimated vertical error in meters, 95% confidence. Present if mode is 3 and DOPs can be calculated from the satellite view.

epx: f32

Longitude error estimate in meters, 95% confidence. Present if mode is 2 or 3 and DOPs can be calculated from the satellite view.

epy: f32

Latitude error estimate in meters, 95% confidence. Present if mode is 2 or 3 and DOPs can be calculated from the satellite view.

Implementations

impl GPSData

pub fn convert_speed(&self, mph: bool) -> f32

Converts the speed from the gps device to miles per hour or kilometers per hour. If mph is true then it’s mph else it’s km/h.

pub fn travel_direction(&self) -> String

Converts the track/heading of travel to the direction N, NE, E, SE, S, SW, W, NW.

pub fn convert_time(&self, timezone: &str) -> Result<String, GPSError>

Takes the time that gps receiver has and converts it to the Time Zone that was given. For more information about the time zone string you can pass check out the crate chrono-tz.

Trait Implementations

impl Clone for GPSData

fn clone(&self) -> GPSData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GPSData

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

Formats the value using the given formatter.

impl Default for GPSData

fn default() -> GPSData

Returns the “default value” for a type.
