Struct RootFinderBuilder

pub struct RootFinderBuilder<'a> { /* private fields */ }

Builder pattern for RootFinder configuration.

Implementations

impl<'a> RootFinderBuilder<'a>

pub fn new(method: RootFindingMethod) -> Self

Creates a new instance of RootFinderBuilder.

pub fn initial_guess(self, guess: f64) -> Self

Sets the initial guess for methods that require one (e.g., Newton-Raphson).

pub fn boundaries(self, x0: f64, x1: f64) -> Self

Sets the boundaries for methods that require bounded intervals (e.g., Bisection).

pub fn tolerance(self, tol: f64) -> Self

Sets the tolerance for the root-finding process.

pub fn max_iterations(self, max: usize) -> Self

Sets the maximum number of iterations.

pub fn log_convergence(self, log: bool) -> Self

Enables or disables logging of convergence steps.

pub fn function(self, function: &'a dyn Fn(f64) -> f64) -> Self

Sets the target function to be used by the root finder.

pub fn derivative(self, derivative: &'a dyn Fn(f64) -> f64) -> Self

Sets the derivative of the target function (required for Newton-Raphson).

pub fn build(self) -> Result<RootFindingIterationDecorator<'a>, String>

Builds and returns the RootFinder instance.
