Trait Implementations

impl Add for &Qty

type Output = Qty

The resulting type after applying the + operator.

fn add(self, other: Self) -> Qty

Performs the + operation.

impl Add for Qty

type Output = Qty

The resulting type after applying the + operator.

fn add(self, other: Self) -> Qty

Performs the + operation.

impl<'b> AddAssign<&'b Qty> for Qty

fn add_assign(&mut self, other: &'b Self)

Performs the += operation.

impl Clone for Qty

fn clone(&self) -> Qty

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Qty

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Qty

fn default() -> Qty

Returns the “default value” for a type.

impl Display for Qty

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&Qty> for f64

fn from(v: &Qty) -> f64

Converts to this type from the input type.

impl FromStr for Qty

type Err = Error

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.

impl Ord for Qty

fn cmp(&self, other: &Self) -> 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 Qty

fn eq(&self, other: &Qty) -> 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 Qty

fn partial_cmp(&self, other: &Self) -> 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 Sub for &Qty

type Output = Qty

The resulting type after applying the - operator.

fn sub(self, other: Self) -> Qty

Performs the - operation.

impl Sub for Qty

type Output = Qty

The resulting type after applying the - operator.

fn sub(self, other: Self) -> Qty

Performs the - operation.

impl<'b> SubAssign<&'b Qty> for Qty

fn sub_assign(&mut self, other: &'b Self)

Performs the -= operation.
