Formats the value using the given formatter.

impl Div for Quantity

type Output = Quantity

The resulting type after applying the / operator.

fn div(self, other: Quantity) -> Quantity

Performs the / operation.

impl From<&str> for Quantity

Creates a Decimal value from a string. Panics if invalid.

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<f32> for Quantity

fn from(value: f32) -> Self

Converts to this type from the input type.

fn from(value: i32) -> Self

Converts to this type from the input type.

impl Into<i32> for Quantity

fn into(self) -> i32

Converts this type into the (usually inferred) input type.

impl Mul for Quantity

type Output = Quantity

The resulting type after applying the * operator.

fn mul(self, other: Quantity) -> Quantity

Performs the * operation.

impl MulAssign for Quantity

fn mul_assign(&mut self, rhs: Quantity)

Performs the *= operation.

impl Ord for Quantity

fn cmp(&self, other: &Quantity) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for Quantity

fn partial_cmp(&self, other: &Quantity) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl SubAssign for Quantity

fn sub_assign(&mut self, other: Quantity)

Performs the -= operation.

impl Copy for Quantity

impl Eq for Quantity

impl StructuralPartialEq for Quantity
