Returns a reference to the metadata.

fn meta_mut(&mut self) -> &mut Bo4eMeta

Returns a mutable reference to the metadata.

impl Clone for Quantity

fn clone(&self) -> Quantity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Quantity

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

Formats the value using the given formatter.

impl Default for Quantity

fn default() -> Quantity

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Quantity

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Quantity

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