Struct EopValues 

pub struct EopValues {
    pub mjd_utc: Day,
    pub pm_xp_arcsec: Option<f64>,
    pub pm_yp_arcsec: Option<f64>,
    pub ut1_minus_utc: Second,
    pub lod_milliseconds: Option<f64>,
    pub dx_milliarcsec: Option<f64>,
    pub dy_milliarcsec: Option<f64>,
    pub ut1_observed: bool,
}

Interpolated IERS Earth Orientation Parameters at a UTC MJD.

Fields carry the units used by the upstream IERS finals2000A.all file:

• pm_xp, pm_yp are arcseconds of polar motion.
• ut1_minus_utc is seconds of time (DUT1).
• lod is milliseconds of time excess over 86 400 SI seconds. It is None whenever the bracketing rows do not both supply a LOD value.
• dx, dy are IAU 2000A celestial pole offsets in milliarcseconds.

Optional fields stay None when either bracketing upstream row leaves the source column blank; the API does not fabricate zero-valued PM or nutation quantities.

pm_yp_arcsec: Option<f64>

ut1_minus_utc: Second

dy_milliarcsec: Option<f64>

ut1_observed: bool

true when both bracketing rows are flagged observed (I).

Trait Implementations

impl Clone for EopValues

fn clone(&self) -> EopValues

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EopValues

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

Formats the value using the given formatter.

impl PartialEq for EopValues

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