Trait EarthOrientationProvider 

Source 
pub trait EarthOrientationProvider: Send + Sync {
    // Required method
    fn orientation_at_tdb_seconds(
        &self,
        epoch_tdb_seconds: f64,
    ) -> Result<EarthOrientation, FrameTransformError>;
}
Expand description

Supplies Earth orientation at a propagator integration epoch.

Force models that need body-fixed coordinates can request this provider from crate::astro::propagator::PropagationContext. The default propagation context carries no provider, so existing forces do not change behavior.

Required Methods§

Source

fn orientation_at_tdb_seconds( &self, epoch_tdb_seconds: f64, ) -> Result<EarthOrientation, FrameTransformError>

Evaluate Earth orientation at absolute TDB seconds since J2000.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
