Struct concordium_std::ExchangeRate

pub struct ExchangeRate { /* private fields */ }

An exchange rate between two quantities. This is never 0, and the exchange rate should also never be infinite.

Implementations

impl ExchangeRate

pub fn new_unchecked(numerator: u64, denominator: u64) -> ExchangeRate

Construct an unchecked exchange rate from a numerator and denominator. The numerator and denominator must both be non-zero, and they have to be in reduced form.

pub fn numerator(&self) -> u64

Get the numerator. This is never 0.

pub fn denominator(&self) -> u64

Get the denominator. This is never 0.

Trait Implementations

impl Clone for ExchangeRate

fn clone(&self) -> ExchangeRate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExchangeRate

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

Formats the value using the given formatter.

impl Deserial for ExchangeRate

fn deserial<R>(source: &mut R) -> Result<ExchangeRate, ParseError>where
R: Read,

Attempt to read a structure from a given source, failing if an error occurs during deserialization or reading.

impl PartialEq<ExchangeRate> for ExchangeRate

fn eq(&self, other: &ExchangeRate) -> 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 Serial for ExchangeRate

fn serial<W>(&self, out: &mut W) -> Result<(), <W as Write>::Err>where
W: Write,

Attempt to write the structure into the provided writer, failing if only part of the structure could be written.
