Struct hydra_dx_math::ratio::Ratio

pub struct Ratio {
    pub n: u128,
    pub d: u128,
}

A rational number represented by a numerator and denominator.

Fields

n: u128

d: u128

Implementations

impl Ratio

pub const fn new(n: u128, d: u128) -> Self

Build from a raw n/d. Ensures that d > 0.

pub const fn new_unchecked(n: u128, d: u128) -> Self

Build from a raw n/d. This could lead to / 0 if not properly handled.

pub const fn one() -> Self

pub const fn is_one(&self) -> bool

pub const fn zero() -> Self

pub const fn is_zero(&self) -> bool

    &self,
    __codec_dest_edqy: &mut __CodecOutputEdqy
)

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere
    F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<(u128, u128)> for Ratio

fn from((n, d): (u128, u128)) -> Self

Converts to this type from the input type.

impl From<Ratio> for (u128, u128)

fn from(ratio: Ratio) -> (u128, u128)

Converts to this type from the input type.

impl From<u128> for Ratio

fn from(n: u128) -> Self

Converts to this type from the input type.

impl MaxEncodedLen for Ratio

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl Ord for Ratio

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Ratio> for Ratio

fn eq(&self, other: &Ratio) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<Ratio> for Ratio

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

This method tests less than (for self and other) and is used by the < operator.

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

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

Serialize this value into the given Serde serializer.

impl TypeInfo for Ratio
