Struct Level 

pub struct Level {
    pub price: f64,
    pub size: f64,
}

A single order-book price level: a resting quantity at a price.

Fields

price: f64

Price of the level (strictly positive).

size: f64

Resting size / quantity at this price (non-negative).

Implementations

impl Level

pub fn new(price: f64, size: f64) -> Result<Self>

Construct a level, validating that price is finite and strictly positive and size is finite and non-negative.

Errors

Returns Error::InvalidOrderBook if the price is not a finite positive number, or the size is not a finite non-negative number.

pub const fn new_unchecked(price: f64, size: f64) -> Self

Construct a level without validation. The caller asserts that price is finite and positive and size is finite and non-negative.

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Level

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

Formats the value using the given formatter.

impl PartialEq for Level

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