Trait Implementations

impl Clone for DensityUnit

fn clone(&self) -> DensityUnit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DensityUnit

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

Formats the value using the given formatter.

impl Default for DensityUnit

fn default() -> DensityUnit

Returns the “default value” for a type.

impl PartialEq for DensityUnit

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