Enum Altitude 

pub enum Altitude {
    Unknown,
    AboveSeaLevel(URational),
    BelowSeaLevel(URational),
}

Altitude relative to sea level.

Combines EXIF’s GPSAltitudeRef (0 = above, 1 = below) with the magnitude from GPSAltitude so the two cannot drift out of sync.

Variants

Unknown

Absent or unparseable.

AboveSeaLevel(URational)

BelowSeaLevel(URational)

Implementations

impl Altitude

pub fn meters(&self) -> Option<f64>

Signed altitude in meters; None when Unknown or denominator=0.

pub fn magnitude(&self) -> Option<URational>

The underlying magnitude rational, regardless of sign. None for Unknown.

Trait Implementations

impl Clone for Altitude

fn clone(&self) -> Altitude

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Altitude

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

Formats the value using the given formatter.

impl Default for Altitude

fn default() -> Altitude

Returns the “default value” for a type.

impl PartialEq for Altitude

fn eq(&self, other: &Altitude) -> 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 Altitude

impl Eq for Altitude

impl StructuralPartialEq for Altitude
