Struct Choice

Source

pub struct Choice { /* private fields */ }

Expand description

A deferred routing decision as contained in a RoutingStep::Choice.

A Choice contains:

candidates: the admissible indices at the current dimension
frame: the residual RoutingFrame describing how routing continues once a choice is made

To continue routing, the caller must select one of the candidates and call Choice::choose to produce the corresponding RoutingStep::Forward.

Implementations§

Source §

impl Choice

Source

pub fn candidates(&self) -> &[usize]

Returns the list of admissible indices at the current dimension.

These represent the valid choices that the caller can select from when resolving this deferred routing step.

Source

pub fn frame(&self) -> &RoutingFrame

Returns a reference to the residual RoutingFrame associated with this choice.

This frame encodes the selection and mesh context to be used once a choice is made, and routing continues at the next dimension.

Source

pub fn choose(self, index: usize) -> RoutingStep

Resolves the choice by selecting a specific index.

Constrains the residual selection to the chosen index at the current dimension and returns a RoutingStep::Forward for continued routing.
