Trait Unit

pub trait Unit: Sized {
    type U;
    type T: Prefix;

    // Required methods
    fn value(&self) -> Self::U;
    fn prefix(&self) -> Self::T;
    fn suffixes() -> &'static [&'static str];
    fn convert(&self, prefix: Self::T) -> Result<Self, String>
       where Self: Sized;
    fn convert_lossy(&self, prefix: Self::T) -> Self
       where Self: Sized;
}

A unit containing a value (ex: an integer), a prefix (ex: an enum), and allowed constant suffix strings.

Required Associated Types

type U

type T: Prefix

Required Methods

fn value(&self) -> Self::U

The value of the unit in the size of its current prefix.

fn prefix(&self) -> Self::T

The current prefix.

fn suffixes() -> &'static [&'static str]

fn convert(&self, prefix: Self::T) -> Result<Self, String>

where Self: Sized,

Convert value to a different prefix, but return an error if the conversion cannot be done without possibly losing precision.

fn convert_lossy(&self, prefix: Self::T) -> Self

where Self: Sized,

Convert value to a different prefix, even if it loses precision.
