Struct Integrator 

pub struct Integrator { /* private fields */ }

Numerical integration configuration.

Implementations

impl Integrator

pub const fn new(subintervals: usize) -> Integrator

Creates an integrator from a subinterval count.

pub fn try_new(subintervals: usize) -> Result<Integrator, CalculusError>

Creates an integrator from a positive subinterval count.

Errors

Returns CalculusError::ZeroSubintervals when subintervals == 0.

pub fn validate(self) -> Result<Integrator, CalculusError>

Validates that the stored subinterval count is positive.

Errors

Returns the same error variants as Self::try_new.

pub const fn subintervals(&self) -> usize

Returns the stored subinterval count.

pub fn trapezoidal<F>( self, function: F, interval: IntegrationInterval, ) -> Result<f64, CalculusError>

where F: FnMut(f64) -> f64,

Approximates a definite integral with the trapezoidal rule.

Errors

Returns CalculusError when the interval or subinterval count is invalid, or when sampled evaluations are not finite.

pub fn simpson<F>( self, function: F, interval: IntegrationInterval, ) -> Result<f64, CalculusError>

where F: FnMut(f64) -> f64,

Approximates a definite integral with Simpson’s rule.

Errors

Returns CalculusError when the interval or subinterval count is invalid, when an odd number of subintervals is used, or when sampled evaluations are not finite.

Trait Implementations

impl Clone for Integrator

fn clone(&self) -> Integrator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Integrator

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

Formats the value using the given formatter.

impl PartialEq for Integrator

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