Enum Direction 

pub enum Direction {
    Prograde,
    Retrograde,
}

Transfer direction for Lambert’s problem.

Prograde means the transfer orbit has positive angular momentum aligned with r1 × r2. Retrograde uses the supplementary transfer angle (> 180°), with angular momentum aligned with r2 × r1.

Variants

Prograde

Transfer angle ∈ (0°, 180°); angular momentum parallel to r1 × r2.

Retrograde

Transfer angle ∈ (180°, 360°); angular momentum parallel to r2 × r1.

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Direction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Direction

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

Formats the value using the given formatter.

impl PartialEq for Direction

fn eq(&self, other: &Direction) -> 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 Copy for Direction

impl Eq for Direction
