Enum CompassZone 

#[non_exhaustive]
pub enum CompassZone {
    Reliable,
    Caution,
    Blackout,
}

How far a compass, and so the declination, can be trusted at a place (report, section 1.8).

The report draws the zones on the ellipsoid’s surface; at height the horizontal intensity weakens (to about 0.7 of the surface’s at 850 km), so the zones there are wider than the report’s. At a rocket’s heights the difference is negligible.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Reliable

Horizontal intensity of at least 6,000 nT.

Caution

Horizontal intensity from 2,000 to 6,000 nT: approaching a magnetic pole, where declination errors exceed 1°.

Blackout

Horizontal intensity below 2,000 nT: near a magnetic pole, where declination errors of up to 180° occur.

Trait Implementations

impl Clone for CompassZone

fn clone(&self) -> CompassZone

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CompassZone

impl Debug for CompassZone

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CompassZone

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CompassZone

impl PartialEq for CompassZone

fn eq(&self, other: &CompassZone) -> 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 Serialize for CompassZone

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
