Struct Quantity 

pub struct Quantity<U: QuantityUnit> { /* private fields */ }

A fixed-point decimal value with a unit, constrained by the QuantityUnit marker U. Encodes to the rich SchemaValue::Quantity.

Clone/Debug/PartialEq/Eq are implemented by hand so the marker type U itself does not need to implement them.

Implementations

impl<U: QuantityUnit> Quantity<U>

pub fn new( mantissa: i64, scale: i32, unit: impl Into<String>, ) -> Result<Self, FromSchemaError>

Constructs a quantity, validating the unit against U.

pub fn from_quantity_value( value: QuantityValue, ) -> Result<Self, FromSchemaError>

Wraps a QuantityValue, validating its unit against U.

pub fn as_quantity_value(&self) -> &QuantityValue

pub fn into_quantity_value(self) -> QuantityValue
