pub struct ExchangeRate { /* private fields */ }
Expand description
An exchange rate between two quantities. This is never 0, and the exchange rate should also never be infinite.
Implementations§
source§impl ExchangeRate
impl ExchangeRate
sourcepub fn new(numerator: u64, denominator: u64) -> Option<ExchangeRate>
pub fn new(numerator: u64, denominator: u64) -> Option<ExchangeRate>
Attempt to construct an exchange rate from a numerator and denominator. The numerator and denominator must both be non-zero, and they have to be in reduced form.
sourcepub const fn new_unchecked(numerator: u64, denominator: u64) -> ExchangeRate
pub const 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.
sourcepub const fn denominator(&self) -> u64
pub const fn denominator(&self) -> u64
Get the denominator. This is never 0.
