Struct PersistentEquivManager 

pub struct PersistentEquivManager { /* private fields */ }

A persistent equivalence manager that supports efficient batch updates.

Unlike EquivManager, this stores equivalences as a sorted list for predictable serialization.

Implementations

impl PersistentEquivManager

pub fn new() -> Self

Create a new empty persistent manager.

pub fn add_equiv(&mut self, a: &Expr, b: &Expr)

Add an equivalence.

pub fn is_equiv(&self, a: &Expr, b: &Expr) -> bool

Check if two expressions are known equivalent.

pub fn len(&self) -> usize

Return the number of stored equivalences.

pub fn is_empty(&self) -> bool

Check if the manager is empty.

pub fn serialize(&self) -> Vec<(String, String)>

Serialize the equivalences to a list of string pairs.
