Struct Fraction

#[non_exhaustive]
pub struct Fraction {
    pub numerator: i64,
    pub denominator: i64,
}

Represents a fraction in terms of a numerator divided by a denominator.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

numerator: i64

The numerator in the fraction, e.g. 2 in 2/3.

denominator: i64

The value by which the numerator is divided, e.g. 3 in 2/3. Must be positive.

Implementations

impl Fraction

pub fn set_numerator<T: Into<i64>>(self, v: T) -> Self

Sets the value of numerator.

pub fn set_denominator<T: Into<i64>>(self, v: T) -> Self

Sets the value of denominator.

Trait Implementations

impl Clone for Fraction

fn clone(&self) -> Fraction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Fraction

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

Formats the value using the given formatter.

impl Default for Fraction

fn default() -> Fraction

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Fraction

where Fraction: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for Fraction

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Fraction

fn eq(&self, other: &Fraction) -> 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 Serialize for Fraction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
