Type Definition uom::si::mass::Mass

pub type Mass<U, V> = Quantity<Dimension, U, V>;

Mass (base unit kilogram, kg).

Generic Parameters

• U: Base units.
• V: Underlying storage type.

Implementations

impl<U, V> Mass<U, V>where U: Units<V> + ?Sized, V: Num + Conversion<V>,

pub fn new<N>(v: V) -> Selfwhere N: Unit + Conversion<V, T = V::T>,

Create a new quantity from the given value and measurement unit.

Generic Parameters

• N: Unit.

pub fn get<N>(&self) -> Vwhere N: Unit + Conversion<V, T = V::T>,

Retrieve the value of the quantity in the given measurement unit.

Generic Parameters

• N: Unit.

pub fn floor<N>(self) -> Selfwhere V: Float, N: Unit + Conversion<V, T = V::T>,

Returns the largest integer less than or equal to a number in the given measurement unit.

Generic Parameters

• N: Unit.

pub fn ceil<N>(self) -> Selfwhere V: Float, N: Unit + Conversion<V, T = V::T>,

Returns the smallest integer less than or equal to a number in the given measurement unit.

Generic Parameters

• N: Unit.

pub fn round<N>(self) -> Selfwhere V: Float, N: Unit + Conversion<V, T = V::T>,

Returns the nearest integer to a number in the in given measurement unit. Round half-way cases away from 0.0.

Generic Parameters

• N: Unit.

pub fn trunc<N>(self) -> Selfwhere V: Float, N: Unit + Conversion<V, T = V::T>,

Returns the integer part of a number in the given measurement unit.

Generic Parameters

• N: Unit.

pub fn fract<N>(self) -> Selfwhere V: Float, N: Unit + Conversion<V, T = V::T>,

Returns the fractional part of a number in the given measurement unit.

Generic Parameters

• N: Unit.

pub fn format_args<N>(unit: N, style: DisplayStyle) -> Arguments<Dimension, N>where N: Unit,

Creates a struct that can be used to format a compatible quantity for display.

Notes

The return value of this method cannot be used to print directly, but is instead used to format quantities and can be reused; see Arguments::with and the examples below.

If you do not need to format multiple quantities, consider using into_format_args instead.

Examples

let t1 = Time::new::<femtosecond>(1.0_E-1);
let t2 = Time::new::<picosecond>(1.0_E-1);
let a = Time::format_args(femtosecond, Description);

assert_eq!("0.1 femtoseconds", format!("{}", a.with(t1)));
assert_eq!("100 femtoseconds", format!("{}", a.with(t2)));

Generic Parameters

• N: Unit.

pub fn into_format_args<N>( self, unit: N, style: DisplayStyle ) -> QuantityArguments<Dimension, U, V, N>where N: Unit,

Creates a struct that formats self for display.

Notes

Unlike format_args, the return value of this method can be used directly for display. It will format the value of self for the quantity on which it is called and nothing else.

If you wish to reuse the return value to format multiple quantities, use format_args instead.

Examples

let t = Time::new::<picosecond>(1.0_E-1);
let a = t.into_format_args(femtosecond, Description);

assert_eq!("100 femtoseconds", format!("{}", a));

Generic Parameters

• N: Unit.

Trait Implementations

impl<U> FromStr for Mass<U, f32>where U: Units<f32> + ?Sized,

type Err = ParseQuantityError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.
