Struct ConversionTable 

Source 
pub struct ConversionTable<Q: Quantity, const N: usize> {
    pub mappings: [(Q::UnitType, Q::UnitType, AmountT, AmountT); N],
}
Expand description

A table defining the conversion between instances of quantity Q having different units.

Each entry of the table is holding the following elements:

  • from_unit: Q::UnitType,
  • to_unit: Q::UnitType,
  • factor: AmountT,
  • offset: AmountT

defining the conversion to_amount = from_amount * factor + offset

Fields§

§mappings: [(Q::UnitType, Q::UnitType, AmountT, AmountT); N]

Table of tuples (from_unit, to_unit, factor, offset), defining the conversion to_amount = from_amount * factor + offset
