1. Heading degrees, True
2. T = True
3. Heading degrees, Magnetic
4. M = Magnetic
5. Speed of vessel relative to the water, knots
6. N = Knots
7. Speed of vessel relative to the water, km/hr
8. K = Kilometers
9. Checksum

Note that this implementation follows the documentation published by gpsd, but the GLOBALSAT documentation may have conflicting definitions.

[GLOBALSAT] describes a different format in which the first three fields are water-temperature measurements. It’s not clear which is correct.

Fields

heading_true: Option<f64>

Heading degrees, True

Trait Implementations

impl Clone for VhwData

fn clone(&self) -> VhwData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VhwData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VhwData

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<VhwData> for VhwData

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for VhwData

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
