class TensorCanonicalizer

Base class for Tensor canonicalizers To make custom canonicalizer make a derived class and install an instance of that class in a Context (see Context::set_tensor_canonicalizer())

Subclassed by sequant::DefaultTensorCanonicalizer, sequant::NullTensorCanonicalizer

Public Types

using index_comparer_t = tensor_index_comparer_t
