pub const fn as_float(self) -> f64

Return the number of meters as a floating point number. This number may be less than 0 (for distances less than a meter), or very large (for kilometers, etc).

Trait Implementations

impl Clone for Meters

fn clone(&self) -> Meters

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Meters

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

Formats the value using the given formatter.

impl PartialEq for Meters

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