Enum Rate 

pub enum Rate {
    OrderRate(OrderRate),
    MaxOrderRate,
    MinOrderRate,
    FeeRate(OrderRate),
    MaxFeeRate,
    MinFeeRate,
}

The Rate enum describes behavior common to rates/prices.

Variants

OrderRate(OrderRate)

MaxOrderRate

MinOrderRate

FeeRate(OrderRate)

MaxFeeRate

MinFeeRate

Implementations

impl Rate

pub fn to_be_bytes( &self, order_precision: u32, fee_precision: u32, ) -> Result<Vec<u8>>

Convert any Rate into bytes for encoding in a Ethereum payload

pub fn from_be_bytes(bytes: [u8; 8]) -> Result<Self>

Create Rate from big endian bytes in Ethereum FillOrder payload

impl Rate

pub fn to_le_bytes(&self) -> Result<[u8; 8]>

Convert any Rate into bytes for encoding in a NEO payload

impl Rate

pub fn to_bigdecimal(&self) -> Result<BigDecimal>

Return new bigdecimal inner value based on Rate

pub fn round(&self, precision: i64) -> Result<Self>

Round in the specified precision.

pub fn invert_rate(&self, precision: Option<u32>) -> Result<Self>

pub fn subtract_fee(&self, fee: BigDecimal) -> Result<OrderRate>

Subtract fee from user by adjusting the order rate downwards

Trait Implementations

impl Clone for Rate

fn clone(&self) -> Rate

Returns a duplicate 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 From<OrderRate> for Rate

Enum wrappers are kind of annoying. This allows us to use .into() on a value to generate a wrapped value. For example: OrderRate::new("1").unwrap().into() => Rate::OrderRate(...)

fn from(rate: OrderRate) -> Self

Converts to this type from the input type.

impl PartialEq for Rate

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