Struct PiecewiseLinear

pub struct PiecewiseLinear {
    pub steps: Vec<(u64, Uint128)>,
}

This is a generalization of SaturatingLinear, steps must be arranged with increasing time (u64). Any point before first step gets the first value, after last step the last value. Otherwise, it is a linear interpolation between the two closest points. Vec of length 1 -> Constant Vec of length 2 -> SaturatingLinear

Fields

steps: Vec<(u64, Uint128)>

Implementations

impl PiecewiseLinear

pub fn value(&self, x: u64) -> Uint128

provides y = f(x) evaluation

pub fn validate(&self) -> Result<(), CurveError>

general sanity checks on input values to ensure this is valid. these checks should be included by the other validate_* functions

pub fn validate_monotonic_increasing(&self) -> Result<(), CurveError>

returns an error if there is ever x2 > x1 such that value(x2) < value(x1)

pub fn validate_monotonic_decreasing(&self) -> Result<(), CurveError>

returns an error if there is ever x2 > x1 such that value(x1) < value(x2)

pub fn range(&self) -> (u128, u128)

return (min, max) that can ever be returned from value. These could potentially be 0 and u64::MAX

Trait Implementations

impl Clone for PiecewiseLinear

fn clone(&self) -> PiecewiseLinear

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PiecewiseLinear

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PiecewiseLinear

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PiecewiseLinear

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for PiecewiseLinear

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

impl Serialize for PiecewiseLinear

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
