Struct CIRSPosition 

pub struct CIRSPosition { /* private fields */ }

Implementations

impl CIRSPosition

pub fn new(ra: Angle, dec: Angle, epoch: TT) -> CoordResult<Self>

pub fn with_distance( ra: Angle, dec: Angle, epoch: TT, distance: Distance, ) -> CoordResult<Self>

pub fn from_degrees(ra_deg: f64, dec_deg: f64, epoch: TT) -> CoordResult<Self>

pub fn ra(&self) -> Angle

pub fn dec(&self) -> Angle

pub fn epoch(&self) -> TT

pub fn distance(&self) -> Option<Distance>

pub fn set_distance(&mut self, distance: Distance)

pub fn remove_distance(&mut self)

pub fn unit_vector(&self) -> Vector3

pub fn from_unit_vector(unit: Vector3, epoch: TT) -> CoordResult<Self>

pub fn to_tirs(&self, eop: &EopParameters) -> CoordResult<TIRSPosition>

Transforms this CIRS position to Terrestrial Intermediate Reference System (TIRS).

The position vector is scaled by distance (in AU) before transformation. If no distance is set, a unit vector is used. The resulting TIRS vector will have the same units (AU or dimensionless) as the input.

pub fn to_hour_angle( &self, observer: &Location, delta_t: f64, ) -> CoordResult<HourAnglePosition>

Trait Implementations

impl Clone for CIRSPosition

fn clone(&self) -> CIRSPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CoordinateFrame for CIRSPosition

fn to_icrs(&self, _epoch: &TT) -> CoordResult<ICRSPosition>

fn from_icrs(icrs: &ICRSPosition, epoch: &TT) -> CoordResult<Self>

impl Debug for CIRSPosition

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

Formats the value using the given formatter.

impl Display for CIRSPosition

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

Formats the value using the given formatter.

impl PartialEq for CIRSPosition

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