Source
pub struct ShapeEquivalence { /* private fields */ }
Expand description

A simple structural equivalence oracle based on shape matching.

Implementations§

Source

pub fn may_be_equal(&self, a: &StructShape, b: &StructShape) -> bool

Return whether two struct shapes can possibly be equal.

Source

pub fn is_expandable(&self, shape: &StructShape) -> bool
