Struct TimeAxis 

pub struct TimeAxis {
    pub origin_s: f64,
    pub mm_per_second: f64,
}

Explicit mapping from a domain time axis to model X coordinates (timelines).

x_mm = (t_seconds - origin_s) * mm_per_second. The mapping is the only place where time becomes length; constraints work on time-dimensioned variables.

Fields

origin_s: f64

Domain time shown at x = 0.

mm_per_second: f64

Model millimetres per second.

Implementations

impl TimeAxis

pub fn new(origin_s: f64, mm_per_second: f64) -> GeoResult<Self>

Create a validated axis.

pub fn to_x(self, t: Quantity) -> GeoResult<f64>

Model X for a time quantity.

pub fn time_at(self, x_mm: f64) -> Quantity

Time at model X.

pub fn width_of(self, duration: Quantity) -> GeoResult<f64>

Model width of a duration.

Trait Implementations

impl Clone for TimeAxis

fn clone(&self) -> TimeAxis

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TimeAxis

impl Debug for TimeAxis

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TimeAxis

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TimeAxis

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for TimeAxis

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
