Struct smoothed_online_convex_optimization::breakpoints::Breakpoints

pub struct Breakpoints {
    pub bs: Vec<N64>,
    pub next: Option<Arc<dyn Fn(f64) -> (Option<f64>, Option<f64>) + Send + Sync>>,
}

Sorted non-continuous or non-smooth points of a function.

Fields

bs: Vec<N64>

Finite vector of breakpoints.

next: Option<Arc<dyn Fn(f64) -> (Option<f64>, Option<f64>) + Send + Sync>>

Function which given a breakpoint returns the previous and next breakpoints (until there are none), respectively. The function is called to obtain the next breakpoint until the piecewise integrals converge to $0$ or the entire integral was integrated.

Implementations

impl Breakpoints

pub fn empty() -> Self

Empty set of breakpoints.

pub fn from(bs: Vec<f64>) -> Self

Generate breakpoints from a finite vector of breakpoints $bs$.

pub fn grid(d: f64) -> Self

Breakpoints on a grid with a mesh width of $d$.

pub fn add(&self, bs: &Vec<f64>) -> Self

Adds breakpoints in $bs$ to the set of breakpoints, unless already included. Note: The caller must ensure that there are no duplicates within $bs$.

Trait Implementations

impl Clone for Breakpoints

fn clone(&self) -> Breakpoints

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Breakpoints

fn default() -> Self

Returns the “default value” for a type.

impl IntoPy<Py<PyAny>> for Breakpoints

fn into_py(self, py: Python<'_>) -> PyObject

Performs the conversion.

impl PyClass for Breakpoints

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
