Trait Implementations

impl Clone for Rate

fn clone(&self) -> Rate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rate

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

Formats the value using the given formatter.

impl Default for Rate

fn default() -> Rate

Returns the “default value” for a type.

impl Display for Rate

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

Formats the value using the given formatter.

impl From<CollateralExchangeRate> for Rate

fn from(exchange_rate: CollateralExchangeRate) -> Self

Converts to this type from the input type.

impl From<Rate> for Decimal

fn from(val: Rate) -> Self

Converts to this type from the input type.

impl Ord for Rate

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<Rate> for Rate

fn eq(&self, other: &Rate) -> 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<Rate> for Rate

fn partial_cmp(&self, other: &Rate) -> 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.

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

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 try_add(self, rhs: Self) -> Result<Self, ProgramError>

Add

impl TryDiv<Rate> for Decimal

fn try_div(self, rhs: Rate) -> Result<Self, ProgramError>
