Struct ConvergenceTracker 

pub struct ConvergenceTracker { /* private fields */ }

Tracks residual progress for an iterative solver and raises Error::ConvergenceFailure when the iteration limit is exceeded.

Implementations

impl ConvergenceTracker

pub fn new( operation: &'static str, max_iterations: usize, tolerance: f64, ) -> Self

Create a new tracker.

Arguments

• operation — human-readable name of the algorithm.
• max_iterations — maximum allowed iterations before failure.
• tolerance — convergence criterion (residual < tolerance ⟹ converged).

pub fn update(&mut self, residual: f64) -> Result<bool>

Record a residual for the current iteration and advance the counter.

Returns Ok(true) if converged, Ok(false) if still iterating, or Err(Error::ConvergenceFailure) if the limit was reached.

pub fn iterations(&self) -> usize

Current iteration count.

pub fn residual(&self) -> f64

Last recorded residual.

pub fn reset(&mut self)

Reset the tracker for reuse.

Trait Implementations

impl Clone for ConvergenceTracker

fn clone(&self) -> ConvergenceTracker

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConvergenceTracker

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

Formats the value using the given formatter.
