Struct Segment

Source

pub struct Segment {
    pub q0: f64,
    pub q1: f64,
    pub p0: f64,
    pub p1: f64,
}

Expand description

A single line segment satisfying q0 ≤ 0 ≤ q1 and p1 ≤ p0

Fields§

§q0: f64

The supply associated to this segment (q0 ≤ 0)

§q1: f64

The demand associated to this segment (q1 ≥ 0)

§p0: f64

The bidding price for the supply

§p1: f64

The asking price for the demand

Implementations§

Source §

impl Segment

Source

pub unsafe fn new_unchecked(a: Point, b: Point) -> (Self, f64)

Construct a simple demand segment from two neighboring points on a demand curve.

Does not check if the points are properly ordered. Additionally returns the amount the points were translated.

Source

pub fn new(a: Point, b: Point) -> Result<(Self, f64), (Self, f64)>

Construct a simple demand segment from two neighboring points on a demand curve, performing validation to ensure the result is valid.

Additionally returns the amount the points were translated.

Source

pub fn slope_intercept(&self) -> (f64, f64)

Compute the slope and p-intercept of the line segment.

Source

pub unsafe fn clip_unchecked(self, qmin: f64, qmax: f64) -> Self

Clip the segment to the provided interval.

Does not validate the requested interval.

Source

pub fn clip(self, qmin: f64, qmax: f64) -> Option<Self>

Clip the segment to the provided interval, returning a value if the interval is valid.
