Expand description

Type for describing a curve over the 2-dimensional space of axes between 0-1, as represented by (Perbill, Perbill).

Variants§

§

LinearDecreasing

Linear curve starting at (0, ceil), proceeding linearly to (length, floor), then remaining at floor until the end of the period.

Fields

§length: Perbill
§floor: Perbill
§ceil: Perbill
§

SteppedDecreasing

Stepped curve, beginning at (0, begin), then remaining constant for period, at which point it steps down to (period, begin - step). It then remains constant for another period before stepping down to (period * 2, begin - step * 2). This pattern continues but the y component has a lower limit of end.

Fields

§begin: Perbill
§end: Perbill
§step: Perbill
§period: Perbill
§

Reciprocal

A recipocal (K/(x+S)-T) curve: factor is K and x_offset is S, y_offset is T.

Fields

§factor: FixedI64
§x_offset: FixedI64
§y_offset: FixedI64

Implementations§

Source§

impl Curve

Source

pub const fn make_linear( length: u128, period: u128, floor: FixedI64, ceil: FixedI64, ) -> Curve

Create a Curve::Linear instance from a high-level description.

WARNING: This is a const function designed for convenient use at build time and will panic on overflow. Ensure that any inputs are sensible.

Source

pub const fn make_reciprocal( delay: u128, period: u128, level: FixedI64, floor: FixedI64, ceil: FixedI64, ) -> Curve

Create a Curve::Reciprocal instance from a high-level description.

WARNING: This is a const function designed for convenient use at build time and will panic on overflow. Ensure that any inputs are sensible.

Source

pub fn info(&self, days: u32, name: impl Display)

Print some info on the curve.

Source

pub fn threshold(&self, x: Perbill) -> Perbill

Determine the y value for the given x value.

Source

pub fn delay(&self, y: Perbill) -> Perbill

Determine the smallest x value such that passing returns true when passed along with the given y value.

If passing never returns true for any value of x when paired with y, then Perbill::one may be returned.

let c = Curve::LinearDecreasing { begin: Perbill::one(), delta: Perbill::one() };
//      ^^^ Can be any curve.
let y = Perbill::from_percent(50);
//      ^^^ Can be any value.
let x = c.delay(y);
assert!(c.passing(x, y));
Source

pub fn passing(&self, x: Perbill, y: Perbill) -> bool

Return true iff the y value is greater than the curve at the x.
