Struct HelmertTransform 

pub struct HelmertTransform {
    pub from: TerrestrialFrame,
    pub to: TerrestrialFrame,
    pub reference_epoch_year: f64,
    pub parameters: HelmertParameters,
    pub rates: HelmertRates,
    pub provenance: &'static str,
}

One published 14-parameter Helmert catalog entry.

Fields

from: TerrestrialFrame

Source frame for the published forward transform.

to: TerrestrialFrame

Target frame for the published forward transform.

reference_epoch_year: f64

Parameter reference epoch, expressed as a decimal year.

parameters: HelmertParameters

Parameters at reference_epoch_year.

rates: HelmertRates

Linear rates of the seven Helmert parameters.

provenance: &'static str

Published table or memo that supplied this entry.

Implementations

impl HelmertTransform

pub fn parameters_at( &self, epoch_year: f64, ) -> Result<HelmertParameters, FrameCatalogError>

Evaluate the seven Helmert parameters at a decimal year.

Trait Implementations

impl Clone for HelmertTransform

fn clone(&self) -> HelmertTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HelmertTransform

impl Debug for HelmertTransform

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

Formats the value using the given formatter.

impl PartialEq for HelmertTransform

fn eq(&self, other: &HelmertTransform) -> 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.
