Struct Speed 

pub struct Speed(/* private fields */);

Implementations

impl Speed

pub const ZERO: Self

pub fn from_knots(value: f64) -> Result<Self>

From knots.

Errors

KernelError::NotFinite for NaN or infinity.

pub fn from_metres_per_second(value: f64) -> Result<Self>

From m/s.

Errors

KernelError::NotFinite for NaN or infinity.

pub fn from_kilometres_per_hour(value: f64) -> Result<Self>

From km/h.

Errors

KernelError::NotFinite for NaN or infinity.

pub const fn knots(self) -> f64

Knots.

pub fn metres_per_second(self) -> f64

m/s.

pub fn kilometres_per_hour(self) -> f64

km/h.

pub fn abs(self) -> Self

Absolute value.

pub fn is_negative(self) -> bool

Whether negative (sternway).

pub fn distance_covered(self, elapsed: Duration) -> Distance

Distance covered in duration.

pub fn time_to_cover(self, distance: Distance) -> Result<Duration>

Time to cover distance.

Errors

KernelError::Indeterminate if the speed is zero or of opposite sign to the distance.
